Workers at the Notting Hill Housing Group in London struck on Monday for the first time in over 15 years.
The Unison union members voted by 93 percent for action.
They are fighting employers’ attempts to attack terms and conditions while rejecting attempts at negotiation.
The cuts include the withdrawal of flexitime, the loss of paid carers’ leave, cuts to salary protection and cuts to relocation expenses.
Workers are particularly concerned that women workers with caring responsibilities would be the hardest hit.
One women worker told Socialist Worker, “The majority of workers here are women with families who will find it difficult to cope.
“If management will do this to us, how will they treat the tenants?
“We don’t know what’s going to happen to those in sheltered housing or those who are sleeping on the streets.
“If we don’t fight now it will be too late for any of us to do anything.”
Notting Hill Housing group, which employs 850 workers, is one of the largest social housing providers in Britain.
