This is now like that final scene in Carry On At Your Convenience. The strike is futile - just get back to the job (presumably you enjoy) and learn from the mistakes this time round. Yes, you lost out on the 4.8%, but that was an error of your own making because some people where under the impression there was more money in the pot without doing the maths.
a lot of 3rd party there vs_lhr, aren't we in this together, did you not lose out on 4.8% too ?
