I’ve noticed they’ll complain that their three months off in summer, their winter break and spring break, plus numerous holidays, are “not enough” and they should get more time off...and they’ll make these complaints right in front of people who have to slave 50 weeks a year to get two lousy weeks off! When I told a teacher once that I only got two weeks’ vacation a year, she almost fainted. “That’s ALL?! Oh, my God! How do you STAND it! You should complain! That’s an outrage!” etc. I think they assume everybody gets as much time off as they do.
That’s why I point to truck drivers as an example of people who are underpaid. Not only are they away from home nearly all the time, they’re paying their living expenses while on the road plus all the bills they have at home.
