Times change, you have been given a good offer, accept it and get on with the job. How much sympathy do you think you will get if you strike over being asked to work until 60? Many of you intend to work over 55 anyway. I well remember a ex BA DEC taking my command years ago and then telling me how his pension was more than the salary he was then getting in the DEC job. If you strike then I'll have your job off you before you know it and then where will your prospects be?
