"9-5" jobs in America are anything but. Since the popularity of smartphones people are reachable 24/7 and employers are taking full advantage.
Hourly employees have it even worse. When your schedule varies week to week and even on your "day off" your employer may be constantly reaching out trying to bully you into taking another shift, it's very hard to maintain regular non-work activities. Perhaps you have friends who work similar schedules to you, but good luck going to a sports team or club that meets Thursdays at 6 when you don't know if you'll be available then until 12 hours before if ever.
