Part time supes complaining about their pay

So I’ve had a few different part time supes complaining about how they didn’t get a raise and some of us are making more hourly or whatever. Had one guy come up and ask if I was also jumping with a driver and immediately started talking about how it must be nice to be taken care of by the company with extra hours. Like I really don’t get it, in my opinion from what I can see, the part time supes don’t really do anything in my building. Most of them are pretty sketchy, always looking for opportunities to cut hourly employees and do union work. It’s not my fault they chose the radio and clipboard over loading and the company hasn’t increased their wages. I mean really what do they expect? If no part time supes showed up for the day our building would operate just fine without them. Most problems we have that occur happen when they short staff it purposely so they can save labor hours. In my opinion they don’t generate any income for this company whatsoever, complete waste of money. People just standing around watching mad about not getting a raise.
