WFH 2 days a week.... the whole thing harkens back to control based management and thinking people are good workers because of how many hours they sit at their desk (she is always here when I am - first in last out, etc) rather than true productivity and value they bring to the enterprise (USS).
Every office I‘ve ever worked in, has aways had at least one of these - gets in before the boss and leaves after the boss. For no other reason, that they think it’s some kind of badge of honour.
The net result was, they end up working two plus hours a day for nothing, for a boss who generally doesn‘t care.
They also tend to be the office grass and not to be trusted at all.
