When the inevitable delayed arrival occurred BNE crew would routinely not accept a reduced slip resulting in disruptions to other crew who were being turned around so that the company could maintain schedules.
Like we all know this is the only form of negotiating that the company understands and is interested in.
If it's legal and they can get away with it they will give it every chance they can.They will only look at it if it starts to cost them money and the way to do that is not to accept reduced slips.
The one thing the company has never understood is that co-operation takes 2 or more people or groups to work together so that the outcome suits all parties.
To them it's always meant they take and you give.
