Workers at Equinox Care, a charity for people in supported housing, struck for two days last week against plans to slash their pay.
The workers, members of the Unite union, faced up to £8,000 pay cuts.
Unite members are also set to strike against pay cuts at One Housing Group sites across London for three days from Wednesday of next week.
And the threat of a strike at St Mungo’s homelessness charity has beaten back plans to impose a 25 percent pay cut to hundreds of workers.
But management is still cutting the rates for new starters.
