Fire Brigades Union members across the region will be out on strike once again this evening.
Tonight's strike takes place between 7pm and midnight.
Further action is planned for New Year's Eve and New Year's Day, in an ongoing dispute over pension reforms.
Contingency plans are being put in place across the Anglia region as firefighters prepare to take part in a four hour nationwide strike.
It's in a row over pension plans.
Emergency calls will still be answered but there may be no response between 12pm and 4pm to calls about things like gas leaks and flooding.
