Keighley firefighters are poised to go on strike again from tomorrow as part of an ongoing dispute regarding planned changes to their pensions.

They are due to take action alongside colleagues across West Yorkshire, prompting fire chiefs to issue a safety alert to the public.

The strike by members of the Fire Brigades’ Union (FBU) is expected to take place tomorrow from noon until 5pm, on Saturday from 2pm until 2am, and again on Sunday from 10am until 3pm.

Further industrial action short of a strike is expected from 3pm on Sunday until noon the following Friday. Such action is where staff can refuse to perform certain parts of their duties.

The row is a national dispute but will not involve control room staff, and it follows a series of short strikes last year.

West Yorkshire Fire and Rescue Service deputy chief fire officer, Steve Beckley, said: “It is disappointing and concerning that negotiations between the government and the FBU have failed to deliver a mutually-acceptable resolution.”

Keighley-based FBU members walked out for six hours on New Year’s Eve and for two hours on January 3. The union is fighting plans to increase employee pension contributions and raise the retirement age to 60.
