Striking workers will picket the Callendar Park offices of the Child Support Agency today (Thursday) as part of a national dispute over pension reform.
Thousands of civil servants are taking part in the 24-hour action in protest at Coalition Government plans to increase individual pension contributions and bring an end to final salary schemes.
Members of the Public and Commercial Services (PCS) union officially downed tools at midnight.
They include staff from Falkirk Sheriff Court and local Jobcentres as well as the CSA office in Falkirk.
All remain open today but services are expected to be severely affected.
The Falkirk Herald understands that around 80 per cent of the 1000 staff based at Callendar Park, who are responsible for processing child benefit payments from across Scotland and the north of England, are taking part in the action.
PCS officials are also hopeful of organising a picket outside Heron House in Falkirk, home of the largest Jobcentre in the area.
David McBride, PCS branch secretary for Forth Valley, said: “We’re expecting a good turnout from members.”
The dispute over pensions has raged for over 18 months.
There are warnings that further strikes will take place in June and later in the year.
