Anytime you want to switch workcenterd it needs to be discussed with your TL and or ETL. The issue could be payroll or it coyld be body count. There may not be a spot for yiu in the old position. It could be a number of things thats store speicific. Keep talking and poking st them. Needle your HR a couole times. Be an annoying fly eventually you may get switched back.
I dont recommend it but yiu can also go to extremes and begin giving up shifts (show uo for the ones not taken big import there) and let othets have the hours as an exclamation point but that csn get messy and put you on a chopping block. Communicate first see where is goes.
