Are you implying that contributing to your company’s success isn’t important? I mean I have helped multiple companies to be successful and by many measures this has provided me success as well. I am pretty sure there is a correlation there.
Exempt employees drawing a salary are pretty much paid on an expect end result more than some arbitrary # of hours the employee works. Hours are meaningless.
The successful companies on the other hand, are planning ahead and taking setbacks into account. Work was done properly so no crazy firefighting. They also don't burn out their employees.
Just my experience of a 43 yo developer.
I think in that case creating a deadline of “we need to put this fire out before it consumes the entire forest” and motivating a bunch of smokejumpers hop in and bust their ass to save the forest isn’t a bad thing.
