PCS members in the Department for Work and Pensions (DWP) were set begin a three-day strike across Merseyside and Halton job centres from Wednesday of this week.
They are fighting plans to cut up to 28 percent of workers. The action involves four branches and workers in 29 offices.
Strikers are inviting support to their picket lines.
They also have a strike rally planned with PCS general secretary Mark Serwotka at 1pm this Thursday on Lord Nelson Street, Liverpool, opposite Lime Street station.

In Nottingham all 44 PCS members in one office were out on strike.
The DVLA strike kicked off a series of planned actions across the Department for Transport.
Driving examiners were set to walk out on Friday of this week.
