Hi A Lurker
The absolute maximum which could be awarded by industrial tribunal is £66k.
My fear is BA would sack 1000 people who would then they would win their tribunal over the following 2 or 3 years (unfair dismissal following legal industrial action)
but it could be a very hollow victory if you had still lost your job & your house.
Please be sure that the potential benefit of successful IA is worth the risk.
