Our Division manager has apperently instituted a new policy concerning call-ins. Drivers who call in for any reason now must use a sick day or they will be coded out as an optional day. This is his way of trying to decrease the number of call-ins. This policy was started last week and since we were not informed we've had a few drivers who have already lost optional days after requesting to not be paid a sick when they called. When our shop steward asked our supervisor he informed him of the new policy then told him even though it isn't in the contract they can still do it so the matter was dead. My question of course is wether they are correct. We are in the Metro DC District and our supervisor wasn't sure if it was district wide or just our division. Alot of us junior drivers bid our optional days as vacation weeks and our supervisor said that we will lose that week if we call in.
