Commission question

So i have been working at my local verizon for almost 6 months now and when i was hired my manager would claim my commissions under the guise of the fact that i was new and he had to walk me through the process and it always sat weirdly with me. Now there is a newer employee that is going through the same thing but at other locations the manager wasn't taking peoples commissions now is this a normal thing or should i contact HR regarding it?
