AstraZeneca staff have been on the picket line for a second time in the ongoing fight to reverse changes to their pensions.

More than 120 GMB union members have staged a walk out at the pharmaceutical giant's Hurdsfield site in protest at plans to curb pension benefits.

A four hour strike today (Wednesday) followed two hour industrial action seven days ago. More protests are planned next Wednesday, with union bosses demanding a return to the negotiating table.

GMB members at the Hurdsfield and Alderley Park sites, which between them employ 6,500 people, had balloted in favour of industrial action last month.

Workers on the picket line today were joined by general secretary of the GMB Paul Kenny and again spoke of their anger at the planned changes.

One employee said: "It is scandalous. We have given more than 20 years service to this company and have previously thought what a good company it is but people will be losing thousands by this. Bosses have upped their pots and taken off ours and it is wrong."

News that AZ chief executive David Brennan is set to walk away with his pension pot of more than £12million has further angered union members.

Mr Kenny said: "It is a scandal and an outrage. We will have a damn good fight; that is what we can guarantee."
