Call centre workers at a Department for Work and Pensions (DWP) office in Garston, Merseyside, completed a five-day walkout on Friday of last week.
The benefits enquiry staff, who are members of the PCS union, are fighting plans to close their office.
The DWP wants to shut the call centre down by May next year and move staff nine miles away to Bootle.
PCS rep Dave Owens said, “In recent years Liverpool has borne the brunt of DWP cuts and many staff in Garston have already been shoved from pillar to post.”
Some 800 Department for Work and Pensions jobs have already gone in Merseyside in recent years, with eight offices closing.
The Garston workers also struck earlier this year but the latest walkout attracted over 40 pickets.
Pickets sent a message of solidarity to tax workers in Merthyr Tydfil who walked out of their office on Thursday of last week after learning that they would be axed.
Dave said, “We need to see that example of solidarity replicated on a national basis.”
