I was recently shorted hrs on my check because the co deducted for breaks never taken

I recently contacted HR to inquire on hrs owed to me which were not documented with a clock in because I had not been given a number to clock in and out with, however the manager scheduled me to work anyways and asked me to record my hrs on my own manually. HR advised me that no hrs had been reported and contacted upper management the following day I was asked why I called HR regarding my hrs and was accused of getting my district manager in trouble. When I did receive my check for said hrs I was shorted by 5.5 hrs because my manager took away for breaks that I did not take due to the fact that i wk graveyard and there are not enough employees to cover for breaks during this shift I also stated in a text message that I was questioning the work ethics of management and the company a few hrs later I was advised that I was not to report for my scheduled shift as my manager requested another employee to come in. And she had my daughter and fellow employee relay the message she never once reach out to me personally to advise me of the change is this considered retaliation for my comments
