I have already contacted the union about this. It is totally unacceptable, I would strongly urge ALL union members to protest in the loudest possible terms to their union reps.
DO NOT take this lieing down. The Level 2 NTC was laughable, saying that this is being introduced owing to in previous years crew members having had 3 or 4 weeks leave in the summer period - I for one in all the years I have been with easyJet not known anyone to have this amount of time off. Also regarding the line that said "reflect a growing business that needs to balance the lifestyle of its crew with an efficient operation" is complete and utter twaddle.
ONCE AGAIN I urge all members to contact your reps, urge the union to take a vote over this (not for industrial acton) to find out whether crew think it is acceptable or unacceptable - the union can then go back to the company about this and press them to rescind the rule.
