Unions meeting at the TUC conference in Brighton have just passed a motion on a General Strike.
It is not calling for a General Strike - there hasn't been one in this country for 86 years - but the TUC is now committed to investigating whether one is feasible and legal.
It is difficult to see that the investigation will take very long. TUC sources admitted before the vote it would be virtually impossible.
It would involve every union member in every company in the UK finding a dispute with their employer in order to legally take strike action.
