Firefighters in the West Midlands are to go on strike today after they rejected a revised pay offer.
The Fire Brigades Union (FBU) met its members last week to discuss the dispute. The disagreement surrounds a compensation deal which the FBU wants for new shift patterns.
The first two walkouts will take place today and next Thursday, leaving the Army to respond to 999 calls.
Members are unhappy about compensation for anti-social hours, travelling long distances and leave arrangements.
A spokesperson for West Midlands Fire Service said the brigade had been notified by the FBU that three-hour walkouts planned for Monday and Thursday would now go ahead.
More than 2,000 union members took part in a ballot last month and voted three to one in favour of strike action.
