HENRY BUTLER,                                     Appeal from the United States District
    Plaintiff-Appellant,                          Court for the Eastern District of Wisconsin.

AMERICAN FOODS GROUP, LLC, and                    J. P. Stadtmueller,

       Henry Butler appeals the grant of summary judgment for his former employer
and its parent company in this employment-discrimination lawsuit. We affirm.

    Butler filed a charge of discrimination with the Equal Employment Opportunity
Commission in April 2009 alleging that American Foods Group and its subsidiary,


      *
        After examining the briefs and the record, we have concluded that oral
argument is unnecessary. Thus the appeal is submitted on the briefs and the record.
See FED. R. APP. P. 34(a)(2)(C).
No. 12-3802                                                                            Page 2

Green Bay Dressed Beef, discriminated against him. He had applied five times to work
for American Foods Group and it denied him employment each time, most recently in
February 2008 when he sought a laborer position. Butler asserted that the five rejections,
all preceding his filed charge by more than a year, were based on his race because, he
says, the company hired Hispanic workers with less experience. (Butler does not
identify his race, but we assume that he is not Hispanic.) Despite the string of rejections,
at a job fair one month after his last rejection, Green Bay Dressed Beef hired him. He
soon injured his back, though, at work in April and December of that year, and after
several absences Green Bay fired him in February 2009. The company stated that it fired
him for violating its attendance policy, but Butler believes that his discharge occurred
because of his back injury and in retaliation for his complaints about the company’s
administration of its attendance policy and a coworker’s sexual comments.

       Butler sued under Title VII of the Civil Rights Act of 1964, 42 U.S.C. §§ 2000e to
2000e–17, and the Americans with Disabilities Act, 42 U.S.C. §§ 12101 to 12213, alleging
that he had been initially denied the laborer job based on race and later fired because of
his back injury and in retaliation for his complaints. The defendants moved for
summary judgment and submitted evidence showing that Butler was fired based on his
multiple, unexcused absences. The district court concluded that the failure-to-hire claim
was untimely because the employer’s latest rejection occurred outside the 300-day filing
period. See 42 U.S.C. § 2000e–5(e)(1). On the discharge claims, the court determined that
Butler had introduced no evidence suggesting that his employer fired him for any
reason other than the one given—his violations of the attendance policy.

       On appeal Butler asserts that his failure-to-hire claim is subject to equitable
tolling. He contends that because the subsidiary, Green Bay, hired him he did not
realize that he had a potential employment-discrimination claim against the parent,
American Foods Group, for not hiring him earlier. But equitable tolling applies only
when a reasonable person acting with due diligence could not have discovered the basis
of a potential claim. See Jones v. Res-Care, Inc., 

, 670 (7th Cir. 2010); Beamon v.
Marshall & Ilsley Trust Co., 

, 860–61 (7th Cir. 2005). Butler does not explain
how or why, after Green Bay hired him, he could not through reasonable diligence learn
the basis of a potential failure-to-hire claim against American Foods Group. Thus,
absent any evidence to support equitable tolling, the district court correctly concluded
that his failure-to-hire claim was untimely.

     Butler next contends that Green Bay should have excused his absences under the
company’s attendance policy; its failure to do so, he says, shows that his employer’s
No. 12-3802                                                                         Page 3

stated reason for firing him was pretext for disability discrimination or retaliation. But
he lacks evidence that Green Bay applied its attendance policy to him any differently
than to co-workers without back problems or those who had made no complaints.
Butler essentially asks us to second-guess his employer’s interpretation of its attendance
rules. The judiciary is not, however, a super-personnel department that reinvestigates
employee disputes. See Harris v. Warrick Cnty. Sheriff’s Dep’t, 

, 449 (7th Cir.
2012); Hudson v. Wal-Mart Stores, Inc., 

, 786 (7th Cir. 2005). Rather, Butler
has the burden to introduce evidence from which a reasonable jury could infer that his
employer fired him based on prohibited grounds (as opposed to enforcing its
attendance policy even-handedly). See Naficy v. Ill. Dep’t of Human Servs., 

,
514 (7th Cir. 2012). The district court correctly concluded that he did not.

                                                                              AFFIRMED.
