I could see if I were a CEO or leadership and saw this over a large sample set I would freak out and implement a RTO. I would realize it is true that clocking in and clocking out may work great on an assembly line a century ago in a factory and people clocking in 15 minutes would hit numbers FAST, however I can't have people logging in only 4 to 5 hours a day.
We have spyware at my employer in which I HATE so my boss let me know when he caught me tired using my phone to log into teams and it was 8am and not 7am that one day. But the other option is he sends me into the office 5 days a week.
But how do you measure productivity? This things are hard. Is it projects? How do you determine the correct labor hours for a project? A previous employer had this drop and they got rid of hybrid work and it is one of the reasons I left.
I like to think we are all adults but I do admit I goofed one day and so has everyone else every now or then. I also have a friend at a bank and he said RTO fixed IT issues like a bank manager needing to get a block removed for a new credit card for a customer. No one would answer in Teams and it was hours later. After RTO instant contact. So return to office was a success and leaders agreed remote work is just not effective and we debated this.
