There are people who fear that if we continue to allow waiving the four days off that we will demonstrate that the four days off are worth nothing to us and the company will get a mediator to take them away from us in the next contract. I don't think that will happen.
I think the company frankly doesn't care about the four days off anymore. Models have been run indicating the staffing requirement is the same either way.
Personally I prefer having the ability to waive as there is no way I could get the work cadence I like being stuck with four day off blocks.
