The Yes voters to MG's RP04 deal agreed to throw away contractual rostering protectiions like 543, work harder for no extra pay, do 12 hour free reserve and give up on the HCMP legal action. In return you got W patterns and a request system. RP04/07 also states you will work to the AFTLS if CX cancels the agreement.
Well guess what; CX have given notice. Who's fault is that? Ask MG or one of the hard to find Yes voters.
