In this action, Prescott sued his former employer, Farmer’s Telephone Cooperative, Inc. (FTC), for unlawful termination. Prescott appeals from the grant of summary judgment to FTC *383on five of his six causes of action. We affirm in part, reverse in part and remand.
I. FACTS
Prescott began working for FTC in 1972 as an inexperienced lineman. Over the years, Prescott was promoted through a number of different jobs until he became a splicer. Prescott testified without contradiction that three supervisors repeatedly told him during the period of his employment that “[a]s long as you did your job [and] kept your nose clean, you’d have a job right on.” Prescott also believed the employee handbooks contained this promise as well.1 Prescott testified he interpreted “keeping your nose clean” to mean “don’t go out there and get into trouble and do things you’re not supposed to be doing,” both at and outside of work.
In 1992, Prescott was assigned to work on a project near Bishopville in Lee County. After the Bishopville job was completed, Prescott was temporarily transferred to work under supervisor Ronnie Joye at the “Cain’s Mill” or Poealla jobsite. During the job, some of Prescott’s co-workers reported that a section of spare cable was missing from where they had left it. A company official named Joe McCants then contacted Prescott and asked him to put his spare cable into the company’s scrap bin. Prescott testified he did so, and also threw away a quantity of insulating sheath, that had come off some of the cable.
A few days later, FTC officials commenced an investigation due to missing cable from both the Bishopville and Poealla job sites. The officials evidently used “sequency markers” printed on the side of the cable to determine that some of Prescott’s spare cable was missing from the scrap bin. District Manager Dent Adams then questioned Prescott, and suspended him pending an investigation. A week later, company officials called Prescott to a meeting and informed him they were terminating him for “lying.” Pursuant to instruction, *384Prescott appealed the decision progressively through company officials until the General Manager affirmed the decision.
Prescott denied taking any cable, and testified that the cable was in the scrap bin for at least a week before Adams questioned him about it. He stated that it was common practice for splicers who needed odd pieces of cable to get them from the scrap bin. Further, while three of Prescott’s co-workers did admit to stealing cable from the Bishopville jobsite, they did not implicate Prescott. Finally, Prescott also testified that a contractor refused to hire him after FTC told the contractor that it would rather Prescott not be hired for any jobs involving FTC.
Prescott filed suit, alleging breach of employment agreement, breach of the implied duty of good faith and fair dealing, defamation, intentional interference with economic relationship, promissory estoppel, and sought specific performance of his employment contract. On a motion for reconsideration, the trial court granted summary judgment to FTC on all claims except the defamation claim. Prescott appeals.
II. SUMMARY JUDGMENT
Summary judgment is appropriate if there is no genuine issue of material fact and the moving party is entitled to judgment as a matter of law. Cafe Assocs., Ltd. v. Gerngross, 305 S.C. 6, 406 S.E.2d 162 (1991). In ruling on a motion for summary judgment, the evidence and the inferences should be viewed in the light most favorable to the nonmoving party. Id.
III. BREACH OF CONTRACT
Prescott first contends the trial court erred in granting summary judgment because material questions of fact exist as to whether FTC breached an employment contract. Prescott points to both the provisions in the employee handbook and the oral representations from his supervisors as altering at-will employment status. The trial judge ruled that the provisions in the handbook did not create an employment contract because they neither addressed duration of employment, nor termination. The trial judge further ruled the oral assurances *385did not set a definite duration for employment so as to alter Prescott’s indefinite at-will employment.
We affirm the trial court’s ruling as to the handbook because we can discern no evidence that FTC breached any of its provisions, even assuming the handbook altered at-will status and created an employment contract. We reverse the grant of summary judgment on breach of contract, however, because a genuine issue of material fact exists as to whether FTC’s oral statements altered Prescott’s at-will status to employment that could only be terminated for cause.
A. General Law
A contract for permanent employment of indefinite duration, which is unsupported by any other consideration than the respective obligations to perform services and pay wages, is terminable at the will of either party. Satterfield v. Lockheed Missiles and Space Co., 617 F.Supp. 1359 (D.S.C.1985) (citing various South Carolina cases). Employment at will results from agreements which have “no additional expression of duration.” Id. (citing Orsini v. Trojan Steel Corp., 219 S.C. 272, 64 S.E.2d 878 (1951)). Of course, at-will employment may be terminated at any time, for any reason, or for no reason at all. Satterfield, 617 F.Supp. at 1361 (citing various South Carolina cases).
However, an employer may modify its workers’ at-will status through written handbooks and oral assurances. See, e.g. Small v. Springs Indus., Inc., 292 S.C. 481, 357 S.E.2d 452 (1987) (Small I). While an employer may insert a conspicuous disclaimer into a handbook which states that the policies contained within will not alter at-will status, an employer may not publish a policy with mandatory language, orally assure the employees that the policy will be followed, and then treat the promise as illusory. Id. See also Kumpf v. United Tel. Co., 311 S.C. 533, 429 S.E.2d 869 (Ct.App.1993). The question is for the fact finder if a handbook and other evidence creates conflicting inferences as to whether the employer altered the employee’s at-will status. Small I, 292 S.C. at 483, 357 S.E.2d at 454; Kumpf, 311 S.C. at 536, 429 S.E.2d at 871.
*386B. Employee Handbook
In most of the South Carolina cases that have dealt with issues similar to those before us, our appellate courts have been faced with handbooks creating a multi-step termination procedure, coupled with mandatory written language and oral assurances that the policy would be followed. For example, in King v. PYA/Monarch, Inc., 317 S.C. 385, 453 S.E.2d 885 (1995), the court affirmed a master’s finding that the employer breached an employment contract by failing to follow the handbook’s procedure that one serious violation or three reprimands would result in termination. The court stated it was inconsequential that the handbook had not been distributed to employees because the plaintiff had been orally informed of the policy. Id. In Fleming v. Borden, Inc., 316 S.C. 452, 460, 450 S.E.2d 589, 594 (1994), the court affirmed the submission to the jury of the existence of an employment contract from a handbook which contained termination provisions. In Leahy v. Starflo Corp., 314 S.C. 546, 431 S.E.2d 567 (1993), the court held that a four-step disciplinary procedure, posted on bulletin boards accessible to employees, created a contractual obligation which altered the at-will status. In Small I, the court affirmed a jury verdict that the employer created an employment contract with a handbook, and then breached it by failing to follow the four-step termination procedure. 292 S.C. 481, 357 S.E.2d 452. Finally, the court held in Bookman v. Shakespeare Co., 314 S.C. 146, 442 S.E.2d 183 (Ct.App.1994), cert. denied, (S.C. July 14, 1994), that a “Sexual Harassment Policy” document limited the employee^ at-will status only to the extent the employer could not fire in retaliation for filing a sexual harassment claim.
In the present case, the relevant policy provisions in the 1979 handbook read as follows:
COMPANY RULES AND REGULATIONS
It is the policy of this company to enforce and establish from time to time reasonable rules that are necessary to facilitate efficient operation and to protect company employees and company property. Violation of the rules listed will subject an employee to reprimand and/or discharge. The rules listed do not restrict disciplinary action from being *387taken on other matters not specifically covered in formal policy.

3. Stealing private or company property

EMPLOYEE RELATIONS (Grievances)
All employees have the right to receive a reasonable answer to any problem, misunderstanding or complaint that he or she may have. Any question should first be discussed with the employee’s immediate supervisor. If the problem cannot be resolved at the immediate supervisory level, both employees (subordinate or supervisor), within a reasonable length of time will arrange a meeting with the department head to obtain a solution to the problem. The department head will have the opportunity to involve our Personnel Manager in trying to arrive at a satisfactory solution.
If all avenues are exhausted, the employee has a right to present his problem to the General Manager without any fear of reprisal. A final decision will be made by the General Manager after consultation with all involved employees. The General Manager’s decision will be final unless the employee seeks an audience with the Board of Directors (which will be granted) or files a grievance with a State or Federal agency.
The grievance provision in FTC’s manual is unlike those discussed in the other appellate decisions, in that it is only a procedure for review of a decision already made, and not a mandatory process before termination can occur. The “Rules and Regulations” provision similarly does not set forth procedures for termination, but merely lists conduct that will subject the employee to some sort of disciplinary action. Neither provision can be read as altering Prescott’s at-will status by requiring cause in order to terminate.
The trial court ruled that the handbook in this case paralleled Epps v. Clarendon County, 304 S.C. 424, 405 S.E.2d 386 (1991), in that the grievance provision does not contain “language such that would inhibit [FTC’s] right to discharge [Prescott].” As noted before, we agree with this conclusion. However, this does not address the right of a terminated *388employee to receive the review set forth in the grievance provision. Assuming without deciding that the review procedure was contractually mandated, we find no evidence that FTC committed a breach by failing to follow the procedure.
Prescott’s own testimony indicates that his termination was reviewed progressively by company officials. First, then District Manager Dent Adams laid Prescott off pending investigation. A week later, Adams, Adams’ future replacement Joe Scruggs, Prescott’s immediate supervisor Charlie Merchant, and Personnel Manager Nicky Nixsen met with Prescott and informed him he was terminated. Later that week, Prescott wrote a letter to the Operations Manager Johnny McDaniel, who reviewed the situation and upheld the termination in writing. Prescott then wrote to FTC’s General Manager, Aubrey Judy, who also informed Prescott in writing that he would not reverse the termination decision. Prescott then ran into Judy a month later and asked him to again review the problem. Judy told him that “if you didn’t do anything and they can’t prove to me that you done anything we’ll work things out.” A week later Prescott received a call from Curtis Kennedy informing him that Judy again upheld the termination. The affidavit of Adams states that Prescott “was afforded an opportunity to file a grievance and seek a review of his termination in keeping with the established grievance procedure.”
Prescott contends FTC did not follow the grievance procedure because it did not consult with “all involved employees.” He states in his affidavit that his supervisor Charlie Merchant and “other employees who knew me well ... would have assured the investigators that they did not believe I was involved in the theft.” However, Prescott himself testified Charlie Merchant was at the meeting when he was terminated. We cannot perceive any reason why Merchant would have been at the meeting if he was not “consulted.” In any event, Prescott testified that his supervisor at the Pocalla jobsite was Ronnie Joye, not Charlie Merchant. We find that FTC substantially, if not completely, complied with the procedure by consulting with “all involved employees” and allowing Prescott progressive stages of review by company officials. The handbook provisions do not provide a genuine issue of material fact because they were not breached. Cf. Cook v. South Carolina *389 Dept. of Highways & Public Transp., 309 S.C. 179, 420 S.E.2d 847 (1992) (no due process violation in termination of highway patrolman because supervisors’ actions were consistent with provisions of the policy manual); Bookman, 314 S.C. 146, 442 S.E.2d 183 (holding that even if the employer breached a promise to conduct a full investigation, the plaintiffs claim failed because she did not contend she was fired in retaliation for filing a sexual harassment claim); Kumpf, 311 S.C. at 538, 429 S.E.2d at 872 (finding a jury question as to breach).
C. Oral Statements
An employer’s oral promises may also become the basis for creation of a contract which limits a worker’s at-will status. Cf. Gaskins v. Firemen’s Ins. Co., 206 S.C. 213, 216, 33 S.E.2d 498, 499 (1945) (noting, in the context of a bilateral contract of insurance, that “if the minds of the parties have met, ... it does not matter whether the form of the contract is written or oral”). See also Small I, 292 S.C. at 484-86, 357 S.E.2d at 454-55 (discussing the unilateral contract principles generally applicable to employment contracts, and noting that the “jury can consider an employee handbook, along with other evidence”); 82 Am.Jur.2d Wrongful Discharge § 101 (1992). Again, if the existence of a contract is disputed and the evidence admits of more than one reasonable inference, the question is for the jury. Kumpf, 311 S.C. at 536, 429 S.E.2d at 871.
In the present case, Prescott claims his supervisors told him on many occasions that “as long as you did your job [and] kept your nose clean, you’d have a job right on.” Conceivably, this statement can be read as a promise that Prescott would only be discharged for cause: either for (1) dereliction of duty, or (2) misconduct inside or outside of work. The trial judge, however, rejected Prescott’s claim that the oral assurances created a contract by citing the rule that:
[U]nder ordinary circumstances a contract to furnish employment permanently, or so long as the employee’s services shall be properly performed, or for a similar indefinite period, is no more than an indefinite general hiring, terminable at the will of either party; and is, therefore, unenforceable as to its duration. (Emphasis added).
Weber v. Perry, 201 S.C. 8, 12, 21 S.E.2d 193, 194 (1942) (holding that the rule did not apply to an employee who gave *390additional consideration beyond his services by abandoning an established business).2 See also Orsini v. Trojan Steel Corp., 219 S.C. at 277, 64 S.E.2d at 880 (1951) (rejecting a plaintiffs claim of breach of oral contract of permanent employment based in part upon the statement — “What do you give a damn? You have a lifetime job here.” — said in response to the plaintiffs desire to give two weeks’ notice to his old employer). In Orsini, the court stated:
“[Pjermanent employment” means steady employment, a steady job, a position of some permanence, as contrasted with a temporary employment or a temporary job. Ordinarily, where there is no additional expression as to duration, a contract for permanent employment implies an indefinite general hiring, terminable at will.
219 S.C. at 277, 64 S.E.2d at 880.
Even if pursuant to an Orsini “durational” analysis Prescott was an employee at will, this does not end the inquiry, as an employer may otherwise alter at-will status. See Small v. Springs Indus., Inc., 300 S.C. 481, 388 S.E.2d 808 (1990) {Small II). Moreover, the above emphasized portion of Weber’s articulation of this rule is inconsistent with Small I and its progeny. In accord with Small I, an employer can be bound by an “express or implied agreement that refers to employment pending the occurrence of some event, such as the employer’s dissatisfaction with the employee’s services or some cause for termination.” 27 Am.Jur.2d Employment Relationship § 34 (1996) (emphasis added). An employer can alter its right to discharge for no reason or any reason, through oral or written statements which constitute a contract to only discharge for cause. Toussaint v. Blue Cross & Blue Shield, 408 Mich. 579, 292 N.W.2d 880, 901 (1980) (Ryan, J., concurring).3 This is precisely the kind of agreement which *391altered the at-will status of the plaintiff in Small I. 292 S.C. at 483-84, 357 S.E.2d at 454 (stating that the jury properly determined: (1) whether the employer’s policies and statements constituted a contract, and (2) whether the employer breached by failing to have a reasonable belief that Small committed a “serious offense,” which under the policy was sufficient to avoid the four-step process and terminate immediately).
We would agree that casual oral remarks are rarely sufficient to alter at-will employment. In Chastain v. Kelly-Springfield Tire Co., 733 F.2d 1479, 1484 (11th Cir.1984), which involved remarkably similar statements,4 the Eleventh Circuit rejected the employee’s claim of an oral offer of an employment contract and quoted Brown v. Safeway Stores, Inc., 190 F.Supp. 295 (E.D.N.Y.1960), for the proposition that a “casual remark made at a meeting, [or] a phrase plucked out *392of context, is too fragile a base on which to rest such a heavy obligation inherent in such a contract.” See also Rowe v. Montgomery Ward & Co., 437 Mich. 627, 473 N.W.2d 268, 273-75 (1991) (noting that “oral statements [creating a contract to terminate only for cause] ... must be clear and unequivocal to overcome the presumption of employment at will,” and must be based on more than “an expression of an optimistic hope of a long relationship”).5 However, in the present case, we give all favorable inferences to Prescott. *393Prescott testified his supervisors repeated the oral promises throughout his twenty years of employment, and this at least gives rise to a question for the jury. Just as an employer should not give written assurances that “are not worth the paper on which they are printed,” an employer should not give oral assurances that are not worth the breath used to speak them. Cf. Small I, 292 S.C. at 485, 857 S.E.2d at 455.
In the 1988 amendment to the handbook, the disclaimer reads: “All employees have the right to terminate their employment at any time, with or without notice, and with or without reason. [FTC] reserves the same right.” The 1991 “Drug Abuse and Drug Testing” policy contains language to the same effect. Prescott claimed his supervisors periodically discussed changes in the handbook, but that he only remembered discussion of changes in insurance benefits. Thus, a question of fact exists as to whether Prescott had actual notice of the disclaimer. If so, the factfinder must determine the disclaimer’s effect on whether any oral promises altered Prescott’s at-will status. Cf. Fleming, 316 S.C. at 463, 450 S.E.2d at 596.
If the fact finder finds a contract to terminate only for cause, he must determine whether the employer had a reasonable good faith belief that sufficient cause existed for termination. Employers cannot be expected to act as judges, so the test is not whether the employee actually committed misconduct, but whether the employer had a reasonable good faith belief that it had cause to terminate.6 Cf. Small I, 292 S.C. at 483-84, 357 S.E.2d at 454. We hold that a genuine issue of material fact exists on the breach of contract claim as to the issues discussed above.7
*394IV. IMPLIED DUTY OF GOOD FAITH AND FAIR DEALING
Prescott contends that the trial court erred in ruling the implied duty of good faith and fair dealing does not apply to employment contracts. We agree. See Shelton v. Oscar Mayer Foods Carp., 319 S.C. 81, 459 S.E.2d 851 (Ct.App.1995), aff'd, 325 S.C. 248, 481 S.E.2d 706 (1997) (only granting certiorari on and addressing the issue of collateral estoppel effect from an Employment Security Commission decision). A genuine issue of material fact exists as to this implied duty if FTC altered Prescott’s at-will status. We reverse the grant of summary judgment on this claim.
V. INTENTIONAL INTERFERENCE WITH CONTRACT
Prescott next contends the trial court erred in granting summary judgment on his claim for intentional interference with contract. The court ruled that “there is no evidence that would be admissible at trial which could sustain [such] a cause of action.” We affirm.
Intentional interference with contract requires three elements: (1) the defendant intentionally interfered with the plaintiffs potential contractual relations, (2) for an improper purpose or by improper methods, which (3) causes injury to the plaintiff. Crandall Corp. v. Navistar Int’l Transp. Carp., 302 S.C. 265, 395 S.E.2d 179 (1990). When ruling on a motion for summary judgment, the circuit court must consider all of the documents and evidence within the record, including the pleadings, depositions, answers to interrogatories, admissions on file, and affidavits. See Anthony v. Padmar, Inc., 307 S.C. 503, 415 S.E.2d 828 (Ct.App.1992); Gilmore v. Ivey, 290 S.C. 53, 348 S.E.2d 180 (Ct.App.1986). A genuine issue of fact can be created only by evidence which would be admissible at trial. *395 Hansen v. DHL Labs., Inc., 316 S.C. 505, 450 S.E.2d 624 (Ct.App.1994), aff'd 319 S.C. 79, 459 S.E.2d 850 (1995).
In the present case, Prescott alleged in his complaint that FTC informed a potential employer that Prescott could not work on jobs involving FTC. FTC denied this allegation in its answer, although it admitted that Prescott “was employed by a contractor who on occasion performed service for [FTC].” Prescott testified:
I told [the contractor] that he would have to get with [FTC] and see if they would let me work with him on sensitive jobs containing [FTC], and so he therefore went to Mr. Joe Scruggs, which took Dent’s place, and Joe told him no, he’d rather I not be involved with anything considered in with [FTC].
The affidavit from Personnel Manager Nixsen states, “... the undersigned is unaware of any statements regarding [Prescott] and/or his termination having been made by FTC employees (other than management directly involved in the investigation and termination)____”
Prescott argues that his testimony as to the contractor’s statement is not hearsay because it contains the admission of a party-opponent, Scruggs. Rule 801(d)(2), SCRE. Even assuming Scruggs’ statement to the contractor is such an admission, Prescott points to no exception applicable to the contractor’s statement to him. The contractor’s statement is an out-of-court statement offered for the truth of the matter asserted, namely, that “Joe Scruggs told me he’d rather Prescott not work on FTC jobs.” Without this evidence, no genuine issue of material fact exists on this cause of action.
YI. PROMISSORY ESTOPPEL
Prescott next contends that the trial judge erred in granting FTC summary judgment on the promissory estoppel claim. The judge ruled that there was no unambiguous promise as the oral statements were “vague oral remarks about job security.” We affirm in result.
In South Carolina, the elements of promissory estoppel are:
*396(1) the presence of a promise unambiguous on its terms; (2) reasonable rebanee upon the promise by the party to whom the promise is made; (3) the rebanee is expected and foreseeable by the party who makes the promise; and (4) the party to whom the promise is made must sustain injury in reliance on the promise.
Woods v. State, 314 S.C. 501, 505, 431 S.E.2d 260, 263 (Ct.App.1993). Assuming Prescott has shown he rebed on FTC’s oral promises, we discern no evidence of injury sustained by Prescott as a result of that rebanee. Thus, we affirm the grant of summary judgment on promissory estoppel.8
VII. CONCLUSION
We reverse the grant of summary judgment on the breach of contract claim. While the handbook provisions provide no basis for breach of contract as there was no genuine issue of fact as to breach, at the very least the following questions remain for the jury: (1) whether FTC altered Prescott’s at-will status through oral statements, (2) whether Prescott had actual notice of the handbook disclaimers, and, if so, whether this affected the creation of an employment contract to terminate only for cause, and (3) if Prescott’s status was altered, whether FTC had a reasonable good faith belief after adequate investigation that it had cause to terminate him.
We also reverse the grant of summary judgment on the claim based on the impbed duty of good faith and fair dealing.
We affirm the grant of summary judgment on the intentional interference with contract and promissory estoppel claims.
Accordingly, the order of the trial court is
AFFIRMED IN PART, REVERSED IN PART AND REMANDED.
