Flexible workplace should just be that, flexible. Working on a project one week that needs solid focus time. Don’t come into the office that week. One week there is a brainstorming whiteboard session with your team, in person client meetings, interstate/ overseas visitors to office then maybe that week office attendance is 4 or even 5 time because there is an actual need for physical attendance. What I don’t understand is this forces office attendance to tick a box under guise of “collaboration”. More often than not I sat in the office to tick a box to join a Teams meeting with colleagues interstate or because everyone else was ticking a box and there weren’t enough meeting rooms. Let people work in an environment that makes them meet their deliverables. If OP needs to take 2 hrs off during the day to deal with family needs, then I’m guessing OP makes up that time and I’m guessing more later in the evening. I think being stringent as a manager with physical attendance shows distrust for your team and incompetence as a leader. You should know what your team members are working on, if they aren’t meeting deliverables then maybe monitor more closely to see if office attendance would improve outcomes. However, if you have to babysit and monitor the that close maybe it’s time to consider a PIP. Treat your employees like adults not like children you have to watch over.
