The "if you don't like it, bugger off" school of thought may have a place when talking about niche operators, however with FR it simply doesn't apply for the vast bulk of the pilot workforce.
Most pilots who start their career with FR will end it with FR due to the scale of it's operation. Put quite simply, there won't be enough available seats for the number of bums (in the physical sense only) who are and will be attracted to the industry.
It appears many haven't grasped this.
