Fair point, but the world is a bigger place than that nowadays. These things never seem very balanced, and organised by people much further up the payscale than you or I. You can try lobbying your unions on these issues, and if there is a case to answer I am sure that they will take it all forward. Sounding off on bulletin boards like this never achieves a great deal, although I know the feeling of having a good rant from time to time.
As it happens I applied for the Canjet contract as I have several thousand hours on the 737, but as I don't have 200 hours on the NG I am not eligible. The 200 hour requirement was requested by the Canadian department for immigration (or which ever relevant department in the Government) to ensure that Canjet were 'importing' an experience level that wasn't available in Canada. I can't believe there aren't sufficient pilots of the advertised experience in the country, but apparently there aren't.
