I started a new job cleaning up a local Macy's in the morning before the store opens. I told them I had experience with some of their heavy equipment, specifically floor buffers and carpet shampooers. They also have a floor scrubber that drives itself and you steer while it polishes the wax and cleans it. I did not have experience on this machine, but I said I was willing to learn. I was handed a manual and received no actual training from anyone. My 8th day there, boss call in sick and the other employee walks out 30 minutes into the shift, I'm there by myself. I call the boss at home to tell her the other girl walked out and she gave me a list of things to do, one of which was run the floor scrubber. The last guy who ran the machine had not done any servicing to it; the return water tank was filled with wet lint and strings and hair that had been sitting in dirty water for some time, because in order to drain the tank completely you have to take a part off of the machine, and that was just too much trouble for him. Anyway, so after all of that I put on clean pads which I later found out were scouring pads when I saw I was actually removing the wax from the floor....not good. Next day I'm asked to do a statement regarding the girl that walked out, and then I'm getting chewed out by the regional manager (in the middle of the store while customers are shopping, fwiw) cursing at me about how it's going to cost him a lot of money to fix this, and all I can say is "I didn't have any training, I told you guys that I hadn't worked a machine like that before" to which he replied "yes you ******* did, (my direct boss) told me that you had experience with that machine." so now it's my word against theirs and they are lying...ok. I take the chewing and then do the statement, after which I stated to my boss that I 'felt like a tool' because I just did them a favor when they just got done screwing me over. she went on to tell me why it was ok because I'd get another chance yadda yadda and if I had tried to hold that letter over their head that I would have gotten fired and this and that. what? today, two weeks later and four more hires come and gone, and I show up to work to see someone I know there for work. so I show him around and tell him everything that I know, which was more information than I was given my first day and we start the work, no heavy machines. boss wasn't there because she had a doctors appt (at 6am, yeah right) so we call her before we leave to find out when new hire has to be in the next day. she then asks me if I'll train him on the floor machine that I already screwed up the floor with... please tell me I'm not going crazy, that I am just in a crappy situation. I'm not going to quit; this is the first job I've had in three years, so I just need to stand my ground and be tactful when I tell her I'm not training him and I'm not going near any of their machines again; because there's a position for that which pays more, and I'm not in it, and I have to do this because you have already thrown me under the bus once. TL;DR - was placed on a piece of equipment I was not trained on. inappropriately operated it without instructions. I'm being asked to train a new employee on that piece of equipment.
