This sounds like what my husband once described in a workplace he once worked at, albeit 30 years ago.
People not wanting to leave work before the boss left........whatever that was supposed to mean.
He knew of an employee who worked long days and weekends thinking she was doing the right thing. No, she was just being used for extra hours by the bosses.
I've worked for a local authority. I did not know the phrase, 'presenteeism' then, but looking back now, that's exactly what was going on.
Staff had their flexi-time cancelled as a cost saving measure. Management grades kept their nine day fortnights. Very nice too.
Especially as a new boss that came along to fill a vacancy saw what an existing boss was getting, i.e. a nine day fortnight. Applied for, and got, the nine day fortnight. Basically, get every other Friday off if you've done the two week's work in nine days. This is done by staying late, short lunch breaks etc.
My time was being monitored so closely I remember once phoning my boss as I was entering the building. This is because it took five minutes to walk up three flights of stairs to the third floor where the office was. Therefore it meant I would not arrive at my desk until 9.05 am. That is a true story.
Basically I suspect someone had whined about my timekeeping so to keep that person sweet, I had to be extra careful about my arrival and returning from lunch. So that person didn't have cause to go whining to my boss again.
However, my boss did once remark to me in a 1-2-1 session that, 'we're all being watched.' I thought, blimey, you too ?
Oh, and the other little gem that the bosses decided upon for us was, 'be at your desk, logged into your phones by 08.55am' Really ? So that adds up to 25mins a week. An hour and a half a month, multiply that by 12 and we're owed time off. No, so how about overtime ? No again ? Who knew. Basically, people were being accused of coming to work, getting a tea or coffee etc then logging into their computer, phone etc.
Even though the operational team we were supporting (who pretty much came and went as they pleased, unless there was someone in who they wanted to gossip with) could do just that.
The quite obvious one rule for one and another rule for others was one of the many reasons I wasn't sorry to leave.
