Tube workers gradually found out via rumour and the BBC that RMT will not, after all, strike on 8 and 10 September. The usual text and email notifications were not sent out. This is presumably because the union never actually officially put the strikes on - instead, it declared its intention to call them - so it hasn't, technically, called them off.
It is not clear what progress has been made to warrant this further suspension of action. We know that Night Tube has been postponed, but with management and the Mayor saying they still intend for it to start in the Autumn, it has not been postponed for long.
And we're keen to know what progress has been made in the dispute over stations job cuts since the unions declared their intention to strike next week.
Unfortunately, keeping up with the comings and goings of the disputes is becoming increasingly difficult for rank-and-file workers. This can drain the morale of members and make it harder to hold solid action when the union leadership's eventually feel that the time is right for it.
