"RMT leader Bob Crow said the strike had been "suspended" to allow the men to take their cases to employment tribunals where they will claim unfair dismissal.
The men - seven in total, although the strike ballot was based on the first five to be dismissed - were fired by employers Metronet, which is responsible for maintenance of more than two-thirds of the network. ........
Mr Crow said the decision to suspend the strike had been taken after Metronet promised that it would abide by the outcome of the employment tribunal."
And as expected there's a bit of Cavalry Ken backlash too: "there was anger among some union members at the Mayor's lastminute intervention.
One accused him of a "cheap publicity shot" by his involvement.
One member said: "He has not got involved at all with this and just wants to get in on the act for publicity purposes to make it look as though he has helped resolve it.
"It is the union's decision what to do in this dispute and not his."
