Dunder Mifflin was a very bad company?
Dunder Mifflin was a very bad company and Michael tried to do his best to keep hi branch engaged, happy and not realise how bad the company actually was.
We can question his methods but I believe he tried to do the things opposite to what he lived during his time as an employee under Ed.
Also, whenever any person from outside of DM Scranton is introduced, we realise how bad either the company was or the people outside were.
Exception: Stamford Scranton merging episode
