yes. as long as you have even 1 employee. You can not have a work environment that is detrimental to the health of your employees.
You know that is untrue. And you also know you do not believe in it.
Hell, I'm watching the Bears/Jets game on TV right now, and football is so much more damaging to one's health than smoking is.
So why not do the world a favor and shut your damn pie hole, you ignoramus 😉
