I guess its that Employee B is always around if ‘something’ goes wrong.
I prefer to work in the evenings so my productivity probably goes up over the course of the day…
Then theres the whole team morale thing…if you hang around for the silly hours you get to know people better…’them and us’ groups form.
I’m sure some companies value employee capability and results more than time spend on seats. Not many though.
I should be working now…ciao.
