Incorporating any changes into the current system presents a number of problems.
Firstly,it makes the current bid system more complex and unwieldy and the company will argue against it for that very reason.
Second,The company is only going to do something which is of benefit to them.
Third,if you try to include changes to the current bid system you are accepting that it is not working and if it goes to a commission or other court the company will use this as an excuse to implement another work system.
So we are faced with 3 possibilities.
1:We accept the proposal put forward by the company whatever that is.
2:We put forward our own model for a work system.
3:We do nothing and try to give other compromises to save the company money.
IF we can accept changes that the company likes then we can keep the current system and that might mean that we get more flying and that means promotion for the junior ranks.
