Second shift schedules ....

My husband works second shift and claims because of this he isn’t on a normal schedule... He wakes up at 1:30pm everyday and gets ready for work. Leaves the house at 2:00pm and has to be at work by 2:30pm. His shift is 2:30-11:30pm. He gets home around 12am and goes to bed 3:30am-4am. It’s so annoying because I never see him. He works 7 days a week, with one weekend off a month. I don’t understand why he can’t get up in the morning like he had a first shift job and when he gets home at night shower and go to bed like most people do. He says it’s because he’s on second shift.... anyone else or their spouse on second shift and it effect them.
