I thought the requirement to publish rosters by a certain time was quietly removed from the OM-A almost a year ago. I can't find any reference in any company manual that requires roster publication at any certain time, so technically can't they publish it on the 31st?
As "Management" recently sternly reminded us, they are not even contractually obliged to provide a roster, or bidding system for that matter.
"No sir, I don't like it!"
