FIREFIGHTERS are set to walk out for a fourth time in a month in an ongoing dispute over pensions.

Announcing the latest strike, the Fire Brigades Union said it was launching a further ballot on other forms of industrial action which will close on December 4.

The union fears firefighters will lose their jobs if the retirement age is raised from 55 to 60 because they may not be as fit.

Brandon Lewis, fire minister, told firefighters on Friday he had withdrawn June proposals on firefighters taking their pension before 60.

The FBU has argued firefighters are likely to experience a decline in fitness in their 50s, meaning they would be unlikely to meet the fitness standards required in the fire service and could face dismissal.

A South Yorkshire Fire and Rescue spokesman said: "We're disappointed another strike date has been announced and call on the government and the FBU to negotiate an end to this dispute as quickly as possible."
