Firefighters in Hertfordshire will join a huge one-day strike by public sector workers next week as part of their ongoing dispute with the Government over pensions.
Members of the Fire Brigades Union (FBU) in Wales and England will walk out next Thursday, when more than a million council and health workers, teachers and civil servants, will be taking industrial action.
The walkout will be the biggest over pay since the coalition came to power, with plans for further strikes later in the year.
The FBU has been involved in a long-running row with the Government over controversial plans to change pensions and the retirement age of firefighters.
The strike will take place from 10am until 7pm.
