A couple of things to add.
Firstly the pilots did have the same agreements but gave them up for a pay restructure which most did very nicely out of or indeed one day will ( and I take the point a very small % lost out ) A large no. of pilots resent the cabin crew working practises as they feel there union sold them down the river
Secondly they are called agreements ie. all parties company,unions, employees agreed to these working practises.
Thirdly if they think these agreements are so good I hear they are still recruiting crew at the rivers
