Not happy?
Boys and girls in the frontend and the hard work area behind, if you have a grieviance then let it be known by sending an email to the author of the letter for when he gets back to work. Let him know who you are and how insulted you feel. Copy this email to your line manager then make sure you save it on your computer.
A couple of hundred emails will demonstrate the level of disgust the management have managed to induce in the past few days.
Then think about joining a union. TGWU is £9.32 a month and means all in together, flightdeck and cabincrew. Either way,those of who are still thinking of staying must stick together. Nobody likes a fight but don't p!ss on me and tell me it's raining.
