MORE than 1,000 ambulance workers in West Yorkshire are being sounded out on the possibility of strike action.
The move comes after leaders of three unions urged their members to reject a "final" pay offer.
The unions - Unison, the T&G and GMB - want workers who earn less than £14,000 a year to get an extra £500 on top of the 3.225% offer.
They are also calling for the working week to be cut to 39 hours or below by September.
Unions also want time-and-a-half to be paid to all staff for overtime and to those who work on off-duty days.
Unison regional officer Steve Hoyland said: "The pay and conditions offer does not show sufficient improvement to warrant acceptance and we are balloting our members over whether they are prepared to take industrial action.
"If they vote for action, we will draw up a timetable for a formal ballot after the indicative ballot is completed on March 11."
