Companies will go to massive lengths to keep from improving pilots T & C's. I believe that the great majority of the management types out their look at the current "difficulties" that they have getting and retainging pilots as a cyclical occurence. Therefore they will do everything they can to keep the conditions low so that when the swing comes back around they still have a lower cost base.
The problem with that mindset is that you may go under in the process as that swing may not come back for 10 years. The old chestnut "paying you more still won't stop you leaving us to go fly a jet, therefore we won't" has finally reached it's use by date and will be the sword by which the bosses will do themselves in on.
It's a sad state of affairs but by no means a new one. I just wonder how long the old mentality can last before businesses start losing work due to having parked aeroplanes.
