Am i overreacting or what?

My husband works 6am-630pm, today he came home at 340pm, and told me they all had to leave at 11am close to 12pm, because of a shut down. And he also told me that one of his manager always get on his ass, because he always gets an hour and a half of free time. Sometimes hed leave at those hours too.

I just wonder wtf he was even doing during those free time, and when they all had to leave the building, what he even did those 3-4hrs. He said he was just chilling w the coworkers, but idk.

Would u feel suspicious of it?
