Angela Rayner is facing embarrassment as more than 1,000 civil servants in her department will go on strike over the right to work from home.
Labour's deputy leader has been accused of failing her own staff despite pushing through a law that gives new powers to workers and trade unions.
She has even refused to meet employees in her Ministry of Housing, Communities and Local Government (MHCLG), according to the Public and Commercial Services Union (PCS), which will walk out when Parliament returns from the summer recess.
More than 1,180 staff will strike on September 1 while 180 staff will down tools for the following three weeks and others will continue long-running industrial action short of a strike.
They are demanding that Ms Rayner – who was spotted sipping wine on the beach in Hove on Tuesday evening – drop the edict that civil servants spend at least three days a week at their desks.
