RMT reps have been back at ACAS over the last couple of days, following on from Wednesday's solid strike. ACAS continues to host a review of London Underground's job-cutting plans.

Now, health and safety reps are working on specific scenarios comparing how safety standards would be maintained comparing current staffing levels with the proposed, lower levels. Meanwhile, stations reps have compiled a report that shows that LU figures used to justify ticket office cuts are inaccurate and that therefore the numbers should be revised.

The review will continue on Tuesday.
