The former leader of the train drivers’ union Aslef has lost his bid to win his job back, despite winning a claim of unfair dismissal.
Shaun Brady, 43, successfully argued at an employment tribunal last year that he had been wrongly sacked, and pursued a claim for re-instatement.
But the Central London Employment Tribunal has decided it would not be practicable to reinstate him as general secretary.
Brady said he would consider whether to launch an appeal.
Keith Norman, Aslef’s general secretary, said: “This verdict is what we have been waiting for in order that the union can finally move on from the past that has dogged us over the last few years.”
