In my limited experience managing people in both the military and civilian world, 10% are worthless, 10% are exceptional, 80% just do what it takes to draw a paycheck.
When you are under-staffed those numbers can get badly skewed, forcing you to keep the dead weight around too long.
Running my business at full speed a few years ago I ran into your issue head first.
A business aquatints of mine me gave some great advise, offer more money to attract better employees. (but screen the applicants better.)
Word spread quickly that I paid photographers and assistance's more than anyone else in Vegas. I still get calls occasionally from former assistance's offering to help out. (If I had the work I would hire)
I had great success with that strategy and will use it again when business improves in the future.
