I work at a really great company were my boss and even my boss's boss really care for me. Because i'm mentally ill, they do stuff like cover for me in talks to the company owner. I pay them back by doing the needed work in half the time that's needed and if they need something "yesterday" they have it before they wake up.
Effectively i am paid for 40 hours on site but do 15 hours on site and deliver 60 hours of work every week. THIS IS NOT ABOUT OVER TIME. The company owner is now demanding that i "work more" eg be on site more. My boss already tried to present the flat numbers of how much better i perform off-site but the owner says he "wants to know his employees better".. My boss and i want to really work this out as smooth as possible, so the question is, are there any KPI or stuff we could buzzword to the owner?
