Working to rule
I remember working in a very large factory when the maintenance engineers and their various helpers were working to rule.
The effect of the work to rule was that the managers, senior engineers and supervisors worked especially hard to make sure that the work was done, to rule, and to plan.
The maintenance organisation had never worked so efficiently and effectively. When the HR bloke got the work to rule ended, the Factory Director was very pissed off with the HR bloke.
The key point for Aviation is that if the managers et al want to make a work to rule work for the organisation, rather than the TU, it can be done, but takes a bit of work.
