London tube drivers to strike across 12 days in spring, says RMT

Union opposed to London Underground pushing ahead with four-day week plan

Tube drivers in London are to strike across 12 days in the spring in a row over a four-day working week, the RMT has announced.

The union said that London Underground bosses were pushing ahead with plans to condense the number of working days in the week, despite their members rejecting the proposals.
