MEMORANDUM OPINION
Plaintiffs Bill Bush, Lloyd Ray Bush, Clyde Nicholas Coris, and J.A. Dowling brought this lawsuit alleging that defendant Liberty National Life Insurance Company discriminated against them because of their age, in violation of the Age Discrimination in Employment Act (ADEA), as codified, 29 U.S.C.A. §§ 621 through 634. Jurisdiction is proper under 29 U.S.C.A. § 626(c)(1) (ADEA) and 28 U.S.C.A. §§ 1331 (general federal question) and 1343 (civil rights). The case is now before the court on Liberty National’s motion for summary judgment, filed December 2, 1997. For the reasons that follow, Liberty National’s motion is granted.
I. SUMMARY JUDGMENT STANDARD
Rule 56(c) of the Federal Rules of Civil Procedure provides that summary judgment is appropriate where “there is no genuine issue as to any material fact and ... the moving party is entitled to a judgment as a matter of law.” Once the party seeking summary judgment has informed the court of the basis for its motion, the burden shifts to the non-moving party to demonstrate why summary judgment would be inappropriate. Celotex Corp. v. Catrett, 477 U.S. 317, 323, 106 S.Ct. 2548, 2553, 91 L.Ed.2d 265 (1986); see also Fitzpatrick v. City of Atlanta, 2 F.3d 1112, 1115-17 (11th Cir.1993) (discussing how the responsibilities on the movant and the nonmovant vary depending on whether the legal issues, as to which the facts in question pertain, are ones on which the movant or nonmovant bears the burden of proof at trial). In making its determination, the court must view all evidence and any factual inferences in the light most favorable to the non-moving party. Matsushita Electric Industrial Co., Ltd. v. Zenith Radio Corp., 475 U.S. 574, 587, 106 S.Ct. 1348, 1356, 89 L.Ed.2d 538 (1986).
II.BACKGROUND
The court finds the relevant and salient background facts to be as follows:
A. Ray Bush
1961: Ray Bush was hired by Liberty National.
October 1981: Ray Bush became a district manager in Jacksonville East, Florida.
November 1991: Ray Bush was demoted from his position as district manager in Jacksonville East, Florida.
December 1991: Ray Bush was reassigned to be a sales manager in Thomasville, Georgia.
August 1998: Ray Bush took a lateral transfer to a sales manager position in Anni-ston, Alabama.
*1254 March 14, 1994.: Ray Bush was demoted from his sales manager position to a position as an agent in Anniston, Alabama.
April 23, 1994: This was the latest date on which Ray Bush could have shown present discrimination based on his October 20,1994, charge with the Equal Employment Opportunity Commission, commonly referred to as the EEOC.
October 20, 1994: Ray Bush filed an EEOC charge based on his 1991 and 1994 demotions. He later alleged that he was constructively discharged in 1996, and that his discharge should be covered under this charge as well. The charge came almost three years after the 1991 demotion, and 220 days after the 1994 demotion.
June 14, 1996: Ray Bush retired, and alleged that he was constructively discharged.
B.Bill Bush
1965: Bill Bush was hired by Liberty National.
1985: Bill Bush became a district manager in Thomasville, Georgia.
August 6, 1993: Bill Bush was demoted from his position as district manager in Thomasville, Georgia.
May 7, 1994: This was the latest date on which Bill Bush could have shown present discrimination based on his November 3, 1994, EEOC charge.
November 3, 1994: Bill Bush filed an EEOC charge based on his August 6, 1993, demotion. The charge came 454 days after the 1993 demotion.
C.Clyde Nicholas Coris
October 1960: Coris was hired by Liberty National.
November 1987: Coris became a district manager in West Palm Beach, Florida.
May 30, 1993: Coris resigned his position as a district manager in West Palm Beach, Florida.
D.J.A. Dowling
Early 1963: Dowling was hired by Liberty National.
July 1991: Dowling became an agent in Bessemer, Alabama.
May 18, 1993: Dowling resigned his position as an agent in Bessemer, Alabama.
E.The Florida Litigation
August 25, 1993: This date was the cut-off date contained in a class-certification order entered by the United States District Court for the Middle District of Florida in the case Hipp v. Liberty National Life Ins. Co., 973 F.Supp. 1033 (M.D.Fla.1997). The order described the class as “All persons who are, or were, employed by Liberty National Life Insurance Company on or after August 25, 1993, who are or were managerial employees, district managers or above, residing in the United States, who were over 40 years of age.” The order was dated February 6, 1996.
February 6, 1996: The United States District Court for the Middle District of Florida entered its certification of the class in Hipp. See August 25, 1993. All four plaintiffs in this case attempted to join the Hipp class even though they did not satisfy Hipp’s class description.
July 28, 1997: The Florida district court granted Liberty National’s motion for summary judgment to dismiss all four plaintiffs in this ease from Hipp because they were “outside the scope of the class as defined by Plaintiffs.” See Hipp v. Liberty Nat’l Life Ins. Co., 973 F.Supp. 1033, 1040 (M.D.Fla.1997).
F. The Instant Lawsuit
August 22, 1997: Bill and Ray Bush filed this lawsuit.
September 18, 1997: Bill and Ray Bush amended their complaint to include Coris and Dowling as plaintiffs.
III. DISCUSSION
In its motion for summary judgment, Liberty National challenges the timeliness of Bill and Ray Bush’s EEOC charges, which underlie this lawsuit. After a careful examination of the evidence presented by the plaintiffs, the court concludes that the evidence demonstrates that the Bushes’ charges were not timely. The untimeliness of their EEOC charges leaves all of the claims in this lawsuit, including those of Coris and Dowl-ing, subject to dismissal. The basis for the dismissal of Bill and Ray Bush’s claims is discussed in the first section below, and the *1255basis for the dismissal of Coris and Dowling’s claims is discussed in the second.
A.
The ADEA’s purpose is to “promote employment of older persons based on their ability rather than age[, and] to prohibit arbitrary age discrimination in employment.” 29 U.S.C.A. § 621(b). To this end, the ADEA has specific provisions prohibiting discrimination in employment because of age, and allowing redress for any violations of this prohibition. See 29 U.S.C.A. §§ 623, 626. One form of redress is the filing of a lawsuit against the allegedly discriminating employer. An employee, however, may not file a lawsuit unless he has timely filed a charge of discrimination with the EEOC “within 180 days after the alleged unlawful practice occurred.” 29 U.S.C.A. § 626(d)(1).1 McClinton v. Alabama By-Products Corp., 743 F.2d 1483, 1485 (11th Cir.1984).
In this case, neither Bill nor Ray Bush filed a charge with the EEOC within the 180-day period after the discriminatory acts they have alleged.2 Nevertheless, because the 180-day bar functions like a statute of limitations and does not serve as a jurisdictional prerequisite to suit, it is subject to the equitable doctrines of waiver, estoppel, and equitable tolling. Zipes v. Trans World Airlines, Inc., 455 U.S. 385, 393, 102 S.Ct. 1127, 1132, 71 L.Ed.2d 234 (1982);3 McClinton, 743 F.2d at 1485. A plaintiff can also be relieved of the bar for claims outside of the period by successfully establishing that he or she has been subject to a ‘continuing violation.’ See, e.g., Miller v. International Tel. & Tel. Corp., 755 F.2d 20, 25 (2d Cir.1985).
In this case, Liberty National timely raised the issue of the timeliness of the Bushes’ EEOC charges, and thus cannot be considered to have waived any right to challenge it. And to invoke the doctrine of equitable tolling, the plaintiffs would have to make a showing that there was some form of excusable neglect for the Bushes’ not filing within the 180-day period, and they have not even suggested this. The plaintiffs therefore do not raise the issue of waiver here, nor do they raise the issue of equitable tolling.
The plaintiffs do assert that Liberty National is precluded from attacking the timeliness of the Bushes’ EEOC charges based on the doctrine of collateral estoppel. The party asserting collateral estoppel bears the burden of proving its application, and, for collateral estoppel to apply, three prerequisites must be shown: (1) the issue at stake must be identical to the one alleged in the prior litigation; (2) the issue must have been actually litigated in the prior litigation; and (3) the determination of the issue in the prior litigation must have been a critical and necessary part of the judgment in that earlier *1256action. Mike Smith Pontiac, GMC, Inc. v. Mercedes-Benz of North America, Inc., 32 F.3d 528, 532 (11th Cir.1994). In this case, the plaintiffs have not satisfied the burden of showing that collateral estoppel applies.
Turning directly to the second prerequisite—that the issue must have been actually litigated in the prior litigation—the plaintiffs rely on one paragraph in the July 28, 1997, order issued by the United States District Court for the Middle District of Florida in the case of Hipp v. Liberty Nat’l Life Ins. Co. That court wrote:
“Moreover, there are other unnamed opt-in Plaintiffs who timely filed with the EEOC; namely, Lloyd Ray Bush, Billy Bush, and Ronald Stell.... Their EEOC charges could be used to establish the temporal scope of the class, so long as their charges sufficiently informed both the employer and the EEOC of the imminent class complaint.... The EEOC charges of Lloyd Ray Bush, and Billy Bush explicitly allege that Defendant engaged in a pattern arid practice of age discrimination- Ronald Stell’s EEOC charge alleges constant threats and harassment as well as the proposition that Defendant was terminating older employees while retaining less productive, younger employees..:. In sum, this Court finds that these EEOC charges sufficiently informed both Defendant and the EEOC of the imminent class complaint. This Court finds that the filed EEOC charges of Plaintiffs Hipp, Stein, McKown, Lloyd Ray Bush, Billy Bush, and Ronald Stell may serve to define the temporal scope of the class and denies Defendant’s summary motion as a matter of law on this point.”
Hipp v. Liberty Nat’l Life Ins. Co., 973 F.Supp. 1033, 1038 (M.D.Fla.1997) (citations omitted).4
Although the Hipp court speaks of the timeliness of the Bushes’ EEOC charges in this paragraph, it is clear from the order that the court’s remark is not a conclusion of any argument or reasoning that the court advances, but is simply made in passing as the court discusses how the plaintiffs can define the temporal scope of the class at issue in the lawsuit. The Hipp court’s eonclusory statement, that “there are other unnamed opt-in Plaintiffs who timely filed with the EEOC; namely Lloyd Ray Bush [and] Billy Bush,” in no way suggests that this issue was “actually litigated” in that case; and, considering that this one sentence is the only mentioning of the issue in the court’s ten-page order, just the opposite is suggested—that there was no litigation on the issue at all.
To support their position that .this issue was litigated, the plaintiffs also provided this court with a copy of Liberty National’s memorandum of law in support of its motion for summary judgment filed in the Hipp case, but this document leads the court to the opposite conclusion as well.5 In this memorandum of law, the issue of timeliness of the EEOC charges is not even raised by Liberty National, and, being as Liberty National would generally frame the issues addressed in the summary judgment context, this suggests very strongly that the issue was not litigated. .
With only one sentence in their favor, and only when taken out of context, the plaintiffs cannot demonstrate that the issue of the timeliness of their EEOC charges was litigated in the Hipp case. In addition, in light of this conclusion, the court need not reach the issues of whether the plaintiffs have adequately shown the first and third prerequisites of collateral estoppel.
Finally, as a means of saving their claims, all of which are based on discrimination that occurred outside of the 180-day period, the plaintiffs argue that they faced a ‘continuing violation.’ The law concerning continuing violations is confused, at best, and the Eleventh Circuit has not spoken specifically on the type of continuing violation alleged here. This situation would normally present a substantial challenge for the court in evaluating the plaintiffs’ claims, because the court would have to divine the various approaches used by the different courts of appeals to consider these issues, determine *1257which approach would be used in the Eleventh Circuit, and then apply that approach to this case. In this case, however, sorting out the law that would be applicable in the Eleventh Circuit will be unnecessary because the plaintiffs cannot succeed under either of the two main approaches used by the various courts. The plaintiffs cannot succeed because they have failed to show that there is any present discrimination, an element that is vital to both approaches, and therefore cannot establish a continuing violation.
The doctrine of the continuing violation allows a plaintiff to revive, and make actionable, time-barred acts of discrimination by connecting them to discrimination that falls within the 180-day filing period. “[I]f both discrimination and injury are ongoing, the limitations clock does not begin to tick until the invidious conduct ends.” Mack v. Great Atl. & Pac. Tea Co., 871 F.2d 179, 183 (1st Cir.1989). The application of the doctrine basically requires that the plaintiff link the time-barred discrimination to some timely discrimination, which can take the form of either another discriminatory act within the 180-day period that is part of a series of related acts, see, e.g., Mascheroni v. Board of Regents of University of California, 28 F.3d 1554, 1561 (10th Cir.1994), or an on-going discriminatory policy that continues to operate into the 180-day period, see, e.g., Bruno v. Western Elec. Co., 829 F.2d 957, 961 (10th Cir.1987). See also Gutowsky v. Comity of Placer, 108 F.3d 256, 259 (9th Cir.) (identifying two types of continuing violations), cert. denied, — U.S. -, 118 S.Ct. 298, 139 L.Ed.2d 229 (1997). In making this showing, it is important to remember that the timely discrimination alleged by the plaintiff cannot simply be a perpetuation of the effects of the past discriminatory acts. Delaware State College v. Ricks, 449 U.S. 250, 258, 101 S.Ct. 498, 504, 66 L.Ed.2d 431 (1980) (citing United Air Lines, Inc. v. Evans, 431 U.S. 553, 557, 97 S.Ct. 1885, 1889, 52 L.Ed.2d 571 (1977)); see also Beavers v. American Cast Iron Pipe Co., 975 F.2d 792, 796 (11th Cir. 1992) (There is a distinction “between the ‘present consequence of a one time violation,’ which does not extend the limitations period, and the ‘continuation of the violation into the present,’ which does.”).
The first means of proving a continuing violation — linking the time-barred discrimination to another discriminatory act within the 180-day period that is part of a series of related acts — is not relevant here. Neither Bill nor Ray Bush has alleged any discriminatory acts to which his time-barred acts can be linked that took place in the 180-day period prior to his EEOC charge. Moreover, in Roberts v. Gadsden Memorial Hosp., 850 F.2d 1549 (11th Cir.1988), the appellate court amended its earlier decision, Roberts v. Gadsden Memorial Hosp., 835 F.2d 793 (11th Cir.1988), to indicate that even where a continuing violation of the first type is shown — that is, linking time-barred discrimination-to another discriminatory act within the 180-day period that is part of a series of related acts — a plaintiff can successfully rely on a continuing violation to revive the time-barred discrimination only where he did not suspect his rights had been violated at the time of the earlier discrimination. Roberts, 850 F.2d at 1550. “A claim arising out of an injury which is ‘continuing’ only because a putative plaintiff knowingly fails to seek relief is exactly the sort of claim that Congress intended to bar by the 180-day limitation period.” Id. In this case, both Bill and Ray Bush suspected that their rights had been violated. Ray Bush thought both of his demotions were age-related,6 and he even filed an EEOC charge based on the 1991 demotion.7 Bill Bush also stated that he found out, within a couple weeks, or possibly months, after his demotion, that he was demoted because of his age.8 Even giving his statements the most favorable reading possible, Bill Bush would have discovered the basis of his demotion many months before the beginning of 180-day period prior to the filing of his EEOC charge. In light of Bill and Ray Bush’s awareness of the basis of their demotions, they would be precluded from stating a continuing violation under the first theory. Presumably, this preclusion would apply to the second theory as well.
*1258With respect to the second means of 'proving a continuing violation — linking the time-barred discrimination to an on-going discriminatory policy that continues to operate into the 180-day period — there are two main approaches. to determining whether a plaintiff has successfully alleged a continuing violation.9 The nature of this type of continuing violation is that “the continuing system of discrimination operates against the employee and violates his or her rights up to a point in time that falls within the applicable limitations period.” Williams v. Owens-Illinois, Inc., 665 F.2d 918, 924 (9th Cir.1982). The first approach used to evaluate whether such a violation exists is illustrated in Abrams v. Baylor College of Medicine, 805 F.2d 528 (5th Cir.1986), and can be called an ‘enforcement’ approach. Under this approach, as long as the discriminatory policy is in effect during the 180-day period, and there is some enforcement of the policy against a plaintiff, that plaintiff would be able to file a timely charge. Id. at 533-34. There heed not be a specific act of discrimination against the plaintiff, but the mere existence of a policy will not suffice to support a timely claim. Id. The second approach is illustrated in Roberts v. North Am. Rockwell Corp., 650 F.2d 823 (6th Cir.1981), and can be called an ‘on-going policy’ approach.10 Under this approach, the mere existence of a discriminatory policy is sufficient, and so long as the policy is in effect, charges under it are timely. Id. at 826-28.
Because this case is in the summary-judgment phase, the court looks directly to the proffers of evidence to determine whether there is sufficient evidence to support a claim of a continuing violation.11 After examining the evidence, the court concludes *1259that the evidence is inadequate to support a claim of a continuing violation. All of the evidence presented by the plaintiffs of a policy maintained by Liberty National — the very least they would have to show under either of the approaches — is from the past, or is not associated with specific dates. This leaves the court with no indication that any discriminatory policy Liberty National may have had existed during the 180-day period prior to the filing of the Bushes’ EEOC charges. Absent this showing, the Bushes cannot demonstrate a continuing violation.
Looking at the specific evidence the plaintiffs have presented to the court, it is all inadequate for various reasons. First, the plaintiffs proffer comments made by Liberty National officials, point to neutral policies adopted by Liberty National that they assert are being used in a discriminatory way, and describe the specific employment actions taken against the named plaintiffs. Again, the vast majority of this evidence focuses on the year 1993 and earlier, and does not indicate that anything happened during the 180-day period prior to the filing of the EEOC charges, or even during the time since then to the filing of this lawsuit. Furthermore, even in trying to develop the evidence of discrimination in the past, the plaintiffs’ analysis of the effects of Liberty National’s policies is very crude, and it reaches very broad conclusions that are not supported by the facts presented. The closest any one event gets is Ray Bush’s demotion in March 1994, but that event is still outside of the 180-day period, and is isolated in time from the rest of the evidence. The plaintiffs also point to some other evidence that is not associated with dates, and the court cannot conclude that a continuing violation occurred based on that evidence.12 Finally, the plaintiffs suggest that there is evidence that is well beyond the filing of the Bushes’ EEOC charges that can support their theory of a continuing violation. However, this evidence is not borne out in their proffers, and this is beside the fact that such later evidence cannot cure the untimeliness of the 1994 EEOC charges.13
*1260One final attempt has been made by the plaintiffs to bolster their allegations of a continuing violation. The plaintiffs have pending a motion for leave of court to amend their first amended complaint, filed March 20, 1998, that would amend the complaint to assert a claim of failure to promote for Bill and Ray Bush. They also add an allegation that both Bill and Ray Bush continued to apply for promotions, but were denied them because of Liberty National’s policies. Even if the court were to grant this motion, and allowed the complaint to be amended, the allegations they make simply are not supported by any evidence, so they would ultimately have to fail.
There is simply not enough evidence to support a claim of continuing violation, and therefore the Bushes are not relieved of complying with the 180-day filing period. Consequently, because Bill and Ray Bush did not file EEOC charges within the 180-day period, summary judgment is appropriate on all of their claims.
B.
Summary judgment is also appropriate as to the claims of Coris and Dowling. Coris and Dowling have never filed EEOC charges, and their only means of participating is to be able ‘piggyback,’ or, as it is also described, invoke the ‘single filing rule,’ with respect to the claims of the Bushes. The process of piggybacking allows a person who does not have a valid EEOC charge to rely on another person’s EEOC charge to satisfy the prerequisites for bringing a lawsuit. Gitlitz v. Compagnie Nationale Air France, 129 F.3d 554, 558 (11th Cir.1997). The doctrine can only be invoked where two requirements are met: (1) the relied upon charge is not invalid; and (2) the individual claims of the filing and non-filing plaintiff arise out of similar discriminatory treatment in the time *1261frame. Grayson v. K Mart Corp., 79 F.3d 1086, 1101-02 (11th Cir.), cert, denied, — U.S. -, 117 S.Ct. 435, 136 L.Ed.2d 332 (1996). In this case, because the court has concluded that the Bushes’ charges are not valid, Coris and Dowling cannot rely on them, and their claims are invalid as well.
IV. CONCLUSION
For the foregoing reasons, Liberty National’s motion for summary judgment will be granted. An appropriate judgment will be entered.
