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.
