Update - my grade was called out for the first week in May and I did join my colleagues on the picket line. It was a fancy dress day and I turned up in a Pikachu outfit (or picket-chu as I was labelled!)
The original offer was 2%. During the strike, it was increased to 4.5%, with an additional 0.5% for the lowest paid. After another "yes" vote to another 6 months of industrial action, today the offer has now included a £1500 flat rate one-off payment. for last year and a commitment to not change the redundancy package until at least 2025.
Our NEC will be discussing it on Monday once the fine print has been looked at and I await their recommendation.
If it helps I've been with my civvy company for 7 weeks and we've all just been given 11.5%.
I'm blown away by it after years of Government abuse. It's a bit like a DV situation, you don't realise how bad the RAF (or possibly CS?) treat you until you go.....
