And how many people sue over losing a landscaping laborer job?
I hate firing people but as the owner it is your job. But the term foreman is thrown around allot and can mean different things to different people and companies. If the guy ran a 2-3 man crew including himself I wouldn't give him that power. But if he supervised the lawn operations and had 20 guys or more under him then yes he would answer to me and they would answer to him and he would have that power.
Middle management does it all the time say you owned a dozen subway franchises you going to tell me the manager of one of them couldn't hire and fire at will. We just happen to have a more hands on owner type of trade and so hiring and firing is traditionally our job but it could be delegated if you choose.
