It does maybe work out better for the GMs, but not as well for the college kids. If you're trying to take classes, classes are typically Monday-Wednesday or Tuesday-Thursday. If you add Sunday to that, you have to work all 40 of your hours in the other four days a week which is brutal. My final semester I ended up having to take a SUNDAY class so it was work four tens M, W, F, Sa, take 15 credit hours on Tuesday-Thursday, take 3 credit hours Sunday morning in a class that was me and a BUNCH of seventh day adventists who also enroll in Sunday courses since Saturday is their sabbath. Keeping up full time hours and trying to schedule 18 hours of school when Sunday isn't an option to work, there are limited courses available in Sunday format at school is definitely challenging.
