CASE 8.2 TRANS WORLD AIRLINES V. HARDISON
432 U.S. 63 (1977)
Background: Larry Hardison, the respondent, worked for TWA, the petitioner, in its Stores Department
in Kansas City. The Stores Department is required to be open 24 hours per day, 365 days per year,
meaning that whenever a job shift is not filled, an employee must be brought in from another
department, or a supervisor must cover. Hardison, and all other employees, were subject to a seniority
system called for in the CBA between TWA and the Union. The seniority system allowed the most
senior employees to have first choice of job and shift, and the junior employees must work when the
union steward cannot find enough people to work a shift.
About a year into his tenure at TWA, Hardison became a member of the Worldwide Church of God. As
a member of this religion, Hardison was required to observe the Sabbath (from sunset Friday to sunset
Saturday) and religious holidays. One day Hardison informed Kussman, the manager, of his religious
convictions. Kussman agreed to notify the union steward to seek a job swap or seek a change in days off
The Appeals Court held that TWA committed an UEP under Section 703(a)(1) of the act because it did
not make a reasonable effort to accommodate Hardison’s religious needs.
Issue: Is requiring an employer to circumvent a seniority system established pursuant to a collective
bargaining agreement between the union and employer in order to accommodate an employee’s religious
beliefs an undue hardship on the conduct of the employers business because it is more than a de minimis
cost?
Decision: Yes. The seniority system is itself a significant accommodation to the needs of all TWA
employees and represents a neutral method for minimizing the chances an employee would have to work
