Can my employer threaten me with termination
I work at a cricket wireless store, I've been working here for 2 years, my employer threaten me with termination if the sign sppiner doesn't sand on the right side of the sidewalk, I've talked to the sign sppiner and he know where he is supposed to be. I work by myself all day and Its really hard to see every movemetn the sign guy does, I stay busy taking payments and helping customers and the side walk is far form the front door, so I can't leave the store to check on him! Today my employer told me he will fire me if the sign guy stands on the wrong side of the side walk again...
So can he fire me for something I don't have control off and something that I didn't do, if the sign guy knows where he is supposed to be, should my employer fire him and not me? Is it legar or right for him to do that?
