The public are being recruited to drive fire engines in case of a strike by West Yorkshire firefighters.
A dispute over pensions recently resulted in a vote for strike action but no dates have yet been set.
Talks were continuing today to try and avert strike action.
But, the West Yorkshire Fire & Rescue Service has a legal duty to provide sufficient emergency cover for communities in such circumstances.
This week it has advertised for temporary Community Response Officers and Driver/Pump Operatives to work from Halifax on flexible hours for £12.50 per hour.
Two cohorts of Emergency Fire Crew are currently training and further crews are now needed to join the team.
Community Response Officers will be trained in firefighting techniques and could be sent out on fires and road traffic collisions under supervision.
Driver/Pump Operators are being recruited to drive fire engines and operate pumps.
The WYFRS said successful applicants will undergo an intensive training programme and be contracted to work a minimum of four hours on a fixed term basis to maintain competence and attend for duty when required throughout periods of industrial action.
The closing date for applicants is September 16.
