Another rail union is set to take strike action
More rail workers are to strike later this month in worsening disputes which threaten travel chaos for passengers.
Unite says that its members employed by Network Rail (NR) as electric control room operatives will join other rail unions in taking action on August 18 and 20.
The Transport Salaried Staffs Association (TSSA) also announced that thousands of its members at Network Rail will strike on the same dates.
The TSSA said it served notice after asking for "clear assurances and clarity" on job security and working practices.
No such assurances were forthcoming and 14 days' notice, required by law, has now been given, said the union.
Unite said the electric control room operatives play a crucial role as they are responsible for managing and controlling the power supply to the rail network.
General secretary Sharon Graham said: "Our members played a crucial role in keeping the rail network functioning throughout the pandemic, ensuring that essential workers and goods could be transported.
"The thanks they get for their sacrifices is an offer that amounts to a kick in the teeth.”
"Our members at Network Rail will receive the union's total support until this dispute is resolved and the workers receive a fair pay deal."
The union said its members are increasingly struggling to make ends meet due to the cost-of-living crisis.
Members of the Rail, Maritime and Transport union and TSSA are striking on August 18 and 20, while members of the drivers' union Aslef at nine train companies will strike on August 13.
