would you fire a gardener if he refuses not to smoke on your Property
I would fire anyone for not following my instructions. Doesn't matter if he understands or not why you don't want him to. You're the boss, he's the employee.
Yes, yes I would
No, that's ridiculous, as long as he disposes of his butts, what's the harm?
Yes of course
You pay him, right, then yes, of course, push him to the curb?
Not if he does a good job and doesn't leave any cigarette butts laying around. Kinda nit picky telling someone they can't smoke outside.
Yes, he is damaging the plants more than he is helping them
