Staff at Forth Valley Royal Hospital are set to strike in a dispute over pay.
99% of trade union UNISON members at Serco have backed walking out over plans to shift pay days from weekly to monthly.
That includes cleaners, caterers, and security staff.
Around 600 workers are to walk out.
UNISON Scotland regional organiser Greig Kelbie said: “Staff at Serco are tired of being pushed around. Their position is clear. This dispute continues until weekly pay remains an option for all those who want it.”
UNISON branch secretary at Forth Valley Health Karren Morrison said: “Low-paid health workers should not be forced into financial hardship just to suit Serco.
“A move to monthly pay risks pushing many into debt. Without a cast-iron commitment that weekly pay will continue, workers believe their finances remain under threat.”
Serco have been approached for comment.
