I'm long since retired, but when I took my last programming job more than 30 yrs ago, with an Israeli owned company in NYC, I vaguely remember the "Introduction to the company" session with HR being a lot about what they expected you to do - including that the hrs you work for the company belonged to THEM. they could not of course tell you what to do in your other hours, but the implication was heavy that in working for them you "belonged" to them ! I learned later that they -prior to my joining them- had a Russian lady working there who had caused big issues with strange behavior with her personal associates brought into the office in nighttime hours, so they were totally primed up in suspicion mode of all things "programmers" ! I loved working there, but learned early on that staying out of office politics was safest, and 'head down, just do your job' made life simpler ! Of course their 'working hours belong to us' policy was a joke considering basically my whole life revolved around that job in the end, but that tends to happen when you love what you do.
