I've been working part-time at Chick-Fil-A for 2 years, and my quit date is set. I'm basically done with that place, so I've been giving up all my shifts to those who want them. Sometimes, however, they will refuse on the basis that they need a certain amount of closers to be men to do the “man” work (cleaning the lobby, mostly). The employees I'm trying to give the shifts to are trained, capable, and willing, and I'm genuinely curious as to whether they have legal grounds to do that or not?
