Is there anybody on here, including WWJD who wants to end employment at will?
Employers are people, which is why the make such glaringly inappropriate and stupid decisions at time, like firing someone because they used to be a male/female, but no longer are.
We are talking about minimal, reasonable restrictions...as we've always discussed. The standard response of mine would be, "fine, then you, as an employer, can handle EVERYTHING on your own, you get no tax benefits..." but that cat has been so far out of the bag for a century that it doesn't even really need saying. (although I just did).
You want to "participate" in our economy that we have built collectively? By all means, please do, it will benefit all of us, but here are some extremely reasonable restrictions:
Don't fire someone for their religion, because they are black, because they are married, because they want to privately f*** their same gender, etc. Feel free to fire them because they can't make doodads quick enough, fire them because they keep stealing paperclips, fire them because they have sincerely bad body odor, fire them for reasons relating to your business, ffs.
