According to Dahlia Lithwick, in regard to the case of Gerald Groff against the U.S. Post Office, "Title VII of the Civil Rights Act of 1964 provides that employers are required to accommodate the religious practices of their employees only if providing such an accommodation does not present [quote] an " ______________ ______________ " to their business, and in some sense Groff is just a case that turns on the meaning of " ______________ ______________ " in trying to determine the nature of a ______________ ______________ for a worker and as Irwin also just told you in a 1977 case, TWA vs Hardison, the Court held that providing a ______________ ______________ imposed an ______________ ______________ on the employer any time it required the employer to [quote] "bare more than a de minimus cost and de minimus, you can tell by the name, means it's a trivial or minor cost."
