That's annoying that they changed the requirements. If they'd left it as flexible as it was, it would help with 'good will' from the good workers like you.My company has been really flexible in that you only go in to the office if and when you want to. Now they are changing tack and there was an announcement from the CEO that we will be required to work 3 days in the office.
What annoys me is the people who are now saying "but I have kids" and "I have a massive commute" when these people worked in this company for years and had their kids when we were all in offices 5 days a week and their commute was the same then!
I know one of the team constantly logs off to drop kids to and from school and appointments and after school activities and then complains she is the only one working late but it's because she is offline for hours during the day. I IM'ed her one day with a question and asked could we have a call and she was down in her mother's house for a chat. Now I do adjust my time for appts but its one every now and again not constantly.
I dont have kids and my commute while not amazing isnt that bad but it still means getting up earlier. Everyone is already asking for exceptions and I think this defeats the entire purpose of a wfh policy. Just because I dont have kids doesnt mean I should have to go in more.
But sounds like some were taking the flexibility too far, with the colleague who popped to her mums etc. She could still have done that, just worked a bit later to make up for it without making a song and dance over it.
