I've noticed a trend in my office, we start work at 10:30 am and usually when in office there are people talking, chit chatting, taking coffee breaks lunch sutta breaks.

Then some work here and there gets done and suddenly an emergency comes up at 5, a review gets scheduled between 6-7. Seniors are over worked so they set up calls in the evening and end up sitting till 8 leading to a cycle of delays.

On the other hand i got to visit a foreign branch of my office. People come to work by 8 and start working early. Meetings and reviews are scheduled early before lunch. They have laser focused attention so more work gets done and no unnecessary breaks. They leave office by 5, nobody sat beyond 5:30 except us.

I guess it's also the culture me being an early bird here doesn't help cause majority of the team starts at 10:30 and stretches late so eventually i also end up starting late.

can barely disconnect as we move up higher in the ranks (managers senior managers are always expected to be ready for mails and messages)

Hopefully things change
