Was told being sent to lumber/building was a demotion, now they're sending me back here, am I getting my hours cut?

As title says. I enjoy being back in lumber and building more than self checkout, I don't like the micro management of the front and the constantly being "on" with customers so I asked "is there a way to be put in building full time?"

The HC I like said "yes but it's sort of a demotion". Fast forward a couple days and they been putting me back here more often which seemed fine to me, but then someone mentioned that it's probably because they're going to/are cutting my hours

It also sucks because this happened soon after I mentioned some issues with one of the HC and the way she treated me.

I guess it be easier to know if UKG app wasn't utter dog shit checking your time cards for anything other than 2 weeks but I haven't been able to compare hours

Is this standard in every store? Does being moved to lumber and building just mean they're demoting me?
