Train people to do their jobs, by giving them all the tools they need. Stop changing processes, keep things simple and stop overwhelming the hard workers. Maybe, have the right people in the right positions?
Hire more people in the service department.
Pay the employees better , hire more people , give the employees coffee or something so they feel valued. Give bonuses, have descent office desks etc. Get rid of the rats in the office and reward the staff so maybe they will stay instead of being stressed out,unappreciated and embarrassed that they work for such a cheap uncaring company/owner
