I work in healthcare and I have every other weekend off except for when someone else is on annual leave, so I get asked to do an extra weekend. I notice that my supervisor never covers someone's weekend shifts, despite the fact she always has weekends off. When I was approached to cover a weekend, I said no. She said why not and I said because I am always doing it and it is someone else's turn (meaning her). She said she cannot do it as weekends are her family time so she will not work it. I said what about my family time then? She said but you still have every other weekend off, and I said yes and you have every weekend off! I did not stand around arguing about it. She's been there for so long that the managers just accept that she will not work weekends but they let me know that it is part of my contract to cover shifts if the business require it. She acts like she's the only one that matters. I shouldn't of argued but I just had enough of doing it when she never does it.
