Emergency control staff from Essex lobbied MPs at parliament over attacks on their working conditions on Wednesday of last week.
The lobby coincided with the end of a nine-day strike over a new shift system that extends the working day from nine to 12 hours.
The workers in the FBU union are also angry at a new computer system which is constantly crashing. They are sick of getting the blame for its problems.
Riccardo la Torre, Essex FBU chair, said, “It was fantastic today seeing our control staff take their case directly to parliament.
“They didn’t come across a single MP who didn’t offer their support. It’s a pity councillors on the fire authority haven’t yet met their own employees themselves.”
