Global Warrior of course its your choice which airline you fly on.
However your posts show hints of naivety with regard to the airline industry. For trainers to take unilateral action against this would be ridiculous & ill-advised. You might not be aware but TREs would also have to answer to the CAA for their actions as they directly represent the authority.
I can assure you that the standards for each stage of training are not compromised for any trainees. If they don't reach the standard then they will not progress. I can also assure you that the CAA have the highest regard for Easyjet training which is much to do with training management as well as the trainers.
