Fire crews across West Sussex have laid down their tools for a 24-hour period of strike action today (Wednesday February 25).
The protest, the latest in a long-running dispute with the government over pensions, commenced at 7am.
The Fire Brigades Union (FBU) said firefighters across the UK have been invited to attend a rally in Westminster today.
Matt Wrack, FBU general secretary, said: “Government ministers have ignored three written requests in the last few weeks by the union to meet to try to resolve this dispute.
“Government ministers are quick to call this union ‘militant’ and yet it’s them who still refuse to talk to us when we remain ready to meet and negotiate at any time.
“Firefighters from all across the UK are attending a rally in Westminster on Wednesday in a ‘No More Lies’ protest aiming to hold this government accountable for the way it has misled parliament, the public and firefighters alike.”
