Nothing brings down an evening like being forced to stay late at work. Even if you are hourly, every so often you'll have that age-old conversation with your boss. "Hey there, bud. Looks like we're extra swamped here today. Would you mind terribly if you stuck around a little bit later than normal? I'd really appreciate it." Your going out clothes languish in your work locker or closet for another several hours as you do tasks that could easily wait until Monday. For all the terrible things about school, at least it ended at the same time everyday. Your teacher's profits were not increased by keeping you late. You couldn't stay late or your teacher would have to deal with some angry bus drivers. In the working world, labor laws have made it so that it is exceedingly difficult for employers to screw you out of money, so they do the best they can to screw your out of time.
