An unofficial strike by drivers at Arriva Trains Wales forced the cancellation of more than 100 trains last Sunday.
The drivers in the Aslef union, who normally work on Sundays as part of their overtime, took the action in protest over pay. They are angry that pay negotiations have dragged on since last summer.
A driver from South Wales told the local paper, “Our basic salary is around £32,000, but drivers for Cross Country, part of the Arriva group, get £47,000. We are not asking for that, but we believe we deserve more.”
Around 100 conductors at London Midland are balloting for strikes over the company’s attempts to force workers to work on Sundays.
The conductors, members of the RMT union, work from depots in Northampton, Bletchley and Watford Junction.
The ballot closes on Wednesday of next week.
Around 250 members of the RMT union working on the Tyne and Wear Metro are to ballot for strikes over moves to privatise the network.
The union says it wants assurances over the future of the Metro, as well as workers’ pensions, pay, staffing levels, jobs and negotiating arrangements.
The plans for industrial action by the workers, who are employed by transport operator Nexus, are part of a wider campaign to keep the Metro in public ownership.
Hundreds of campaigners attended a public meeting in Newcastle last week to protest at the privatisation plans.
Nexus has denied that it is privatising the Metro but has recently announced a shortlist of bids to run the system, including bids from several multinational transport companies.
Around 130 workers at the C2C rail operator are to strike for 24 hours on Monday of next week over holiday entitlement.
The workers, members of the RMT and TSSA rail unions, voted overwhelmingly to strike after management refused to grant 28 days holiday.
workers responsible for finding and fixing power faults on London Underground were set to strike overnight on Tuesday and Sunday this week.
The 24 workers also struck last week and three times before Christmas. The workers, members of the RMT union, are employed by EDF Energy Powerlink. They want parity with non-shift colleagues.
Further strikes are planned for 22 February and 1 March.
