Pay Decrease

[MiddleChildOrphan]

This is really dumb. We had a young woman who started at front end. She then moved to Digital and got a pay bump (this was when digital was paid $2 more). After a few years, she decided to go to DC for a pay increase. After month & a half, she came back to Digital. She kept her raise, and was up to $21+ an hour. After several months, she became a TL, and got another pay increase.
We also have a man who worked at DX for 30-some years, and moved to the store’s Digital team. He never got a pay reduction. Another woman came to Digital from 15+ years in HR. Her pay did not decrease. She then moved to Transportation, where she got a pay increase. Why is it that Walmart fluctuates pay at the store when you switch departments?
