Thank you. I was reprimanded once for essentially "only" being at the office for the defined time we agreed I would be there. I spent some time racking my brain until I decided I wasn't being unreasonable.
In the U.S., while I think it's true that people tend to work closer to 50 hours, we pay lip service to the "40 hour work week".
In our industry where it tends to be an option for us, "find a new job" might make sense.
