You didn’t read the comment. It’s not about getting a job in a restaurant within 1 mile - but rather opening a restroom yourself in that radius.
I don’t think it’s fair if they leave you without a chef and open a new restaurant selling the same kind of cuisine down the bock tomorrow.
That seems more like a spite restaurant. And I’m ok with putting a simple time/distance limit on that. Next year? Nearby city? Different kind of food? Go for it tomorrow.
I’ve tried to come up with a comparable situation where the roles are reversed. Suppose that you owned a restaurant. If you fire your chef and buy your local competitor, can the chef argue that this purchase shouldn’t be allowed because he can’t get a job in the local market anymore?
