You have to be quite spectacularly dumb to lose an Employment Tribunal as an employer. The Employment Tribunal is not an appeal court, they will not overturn an employer’s decision if that employer followed their dismissal process correctly. The Tribunal takes a very wide view of what a reasonable employer would decide. Unless you have a protected characteristic or the employer is daft enough to have put their shenanigans in writing, it is almost impossible to win as an employee.
The trade unions, especially the RMT, have long since lost any faith in the Employment Tribunal system. I share their opinion.
The fact that all their colleagues are prepared to lose wages in order to protest their dismissal is more telling. If their colleagues knew they were bang to rights they wouldn’t be on strike.
Of course,
you would have that opinion; it's a given, but I'd take any such view with a pinch of salt. I am not sure that the concerns of colleagues can be dismissed so easily if you don't know anything about the matter.
Your bogus claim reminds me of the 2013 incident where a well-known Swansea City hooligan, who worked for GWR, misbehaved on a train back from the London area to Swansea after match, and was sacked. However, a strike then followed to attempt to reinstate him. A GWR train manager (who, before had to retire from that position due to ill health a few years after this event) who was a regular on this forum told me that no-one wanted to vote
against strike action on principle, but that most colleagues did not support strike action and accepted that the sacking was legitimate, but still had to go on strike anyway, due to solidarity reasons. There was a thread or two about this at the time, but I can't find it now. I am
not suggesting there are any parallels in this case, but merely debunking the claim you make in your post.
