Paramters are defined contractually before implementation, to the extent possible.

PBS Implementation will have full union oversight, and union will have full veto authority if it's not working out.

Any tweaks approved during implementation become contractual. Future tweaks of ANY parameter require either contractual allowance or union concurrence.

Contractual rules about pairing construction, or just let the union build pairings. That can be done within certain parameters defined by the company, but avoids stupidly wasteful pairings which result from sheer laziness of staff (seen that before).

PBS can be be win-win, you just have to fence off the territory in PBS where the company could achieve a windfall by abusing the system at the expense of the pilots. And it's not really rocket science, most airlines have PBS so there are plenty of examples to learn from (both good and bad).
