SIPTU members employed by the Irish Wheelchair Association (IWA) are to go on strike on Tuesday 5 July as part of a pay dispute.
The work stoppage will affect IWA care centres across the country after SIPTU members voted overwhelmingly in favour of taking the industrial action.
They say they have not received a pay increase for 14 years and that although they do essentially the same job as HSE healthcare assistants, they are paid considerably less.
"It is with heavy heart our members have decided they have no other option but to conduct industrial action to advance their long running claim for pay justice," said SIPTU Public Administration and Community Division Organiser Adrian Kane.
"This dispute is a direct result of a failure by the Government to engage with unions representing workers throughout the care and community sector on pay and conditions," he added.
The strike at the Irish Wheelchair Association is part of a wider co-ordinated campaign of upcoming industrial action at community, care and Section 39 organisations which is backed by SIPTU, Fórsa, INMO and ICTU.
As part of their campaign for better pay and conditions, community workers held a protest in Dublin last month.
The Department of Health has previously said that because Section 39 organisations are privately owned, setting pay rates for their staff is not a matter for the Government.
