You don't need a union to have effective management. It should also be their incentive not to cause people's death by overworking employees. Which is also dumb because it costs more to overwork then hire appropriately with overtime laws... cops exploit this all the time to steal money from taxpayers. (The ones in Seattle only get caught when they accidently charge over 24 hours of overtime in a day)

Union rules that say only a particular classification of employee is allowed to pick up a small package from a loading dock and move it twenty feet are also bad.

The blame can go to the top, for not managing correctly.

> It should also be their incentive

You can't just proclaim what incentives should be. We do have a mechanism for changing the incentives of management though: it's called unions.
