there is definitely different circumstances. With 80 union guys, you can not tolerate that. But you can also afford to fire the guy, call the hall and have another guy sent out the next day.
with a 4 man shop, you can't afford to do that for every little thing. You are at the mercy of your employees until you hit probably 10-12 men. Even then you are only a couple of disgruntled employees away from disaster...
