This is the only legal answer you should listen to, because it's the only one with a minimal chance of biting you in the ass: Ask an actual lawyer familiar with your state's laws. If my memory's failing again, and you're outside the U.S., replace state with whatever applicable lowest scale of jurisdiction you're under. Whatever statement other than that, general or specific, any of us can give, can become completely off base depending on the state of your local legislature. To a one, they will all be fundamentally bad advice unless for some bloody weird reason someone that's licenced for practice in your area shows up -- and then it may be even more likely to be terrible, because a lawyer giving legal advice online on a random forum and in response to that much information is what can be colloquially called "fuckstupid".
More asspully, I'd be willing to wager a very small amount of non-money it would largely hinge on your area's stance regarding at-will employment. If your lot's on board with it, and they probably are state side, you very likely won't have grounds for shit because they can fire you for any reason, including none, and the only legal recourse you would have is if they're doing it for reasons discriminatory towards a protected class. And the leniency patterns towards a single person not you is almost certainly not going to be enough to prove that was the motivation for your firing, especially if it's prefixed by you starting to do stuff people are normally fired over.
