The union has issued a strike notice after it claimed the NI Housing Executive failed to make any pay offer.
The strike, which is due to last four weeks will involve 300 Unite members and will start on Monday 5 September.
A spokesperson for Unite said: “The strike has been called after management failed to make any offer whatsoever to improve pay and meet the pay claim of Unite members.
"Workers’ demands include a cash payment alongside a consolidated two pay point increase above the (National Joint Council) national pay offer for 2021-22, which is a bare 1.75 percent. Workers at the Housing Executive engaged in two strikes earlier in the year but the latest announcement represents a clear escalation.”
Unite general secretary Sharon Graham offered her full support to the Housing Executive workers. She said: “Retail price inflation is already above 12 percent and is widely forecast to hit 18 percent by the end of the year. In such a cost of living crisis, workers need a decent pay increase to protect themselves and their families.
“In announcing this four week strike, the Northern Ireland Housing Executive workers can count on the full support of my union as they fight to win a decent pay increase. The NIHE should make an offer to the workers and they should do that as soon as possible.”
Regional Officer for Unite, Michael Keenan laid the blame for the continued strike action squarely at the feet of employers and warned that the strike was likely to have a severe impact on housing executive services. He said: “NIHE bosses failed to bring forward any concrete proposals to address the pay claim of Unite’s members. They have left their employees with no alternative but to recommence strike action.
“Workplace representatives at the Housing Executive are reporting that the service is already facing huge pressures. We are warning that bosses are bringing about a strike that will have potentially severe impact on the services offered by the Housing Executive to tenants. The blame for this rests entirely with the Housing Executive which has failed to seriously attempt to resolve this dispute.”
A spokesperson for the Housing Executive said: “We have been made aware of further planned industrial action by Unite the Union commencing 5 September.
“During this period of industrial action we will seek to ensure that any impact on customer service is minimised.”
