I didn't receive a raise in August 2021 as a cover driver in the western region. On November 1st, 2021, my pay was dropped by another $1.10 an hr. Payroll's explanation was that I'd been coded as a full-time driver and as such my pay was corrected (which is incorrect). I've talked to every supervisor, manager, shop steward, and business agent in my building. I have filed a grievance on this a year ago and still haven't gotten anywhere. What can I do to get this resolved? Hire a lawyer?
