The Rail, Maritime and Transport (RMT) Union is set to ballot members working out of the Stratford and Greenwich depots of the Jubilee Line.
The union has written to London Underground, listing the following grievances:
- The "unfair and disproportionate" treatment of Drivers in disciplinaries
- Facilities on the Jubilee Line "being in a very poor and in some cases a disgusting state"
- The "removal and threatened removal of some benefits"
- A "severe lack of support" from managers for their staff.
