More than 80% of Unite union members at a north-east housing firm have voted to strike over pay.
About 40 employees at the Aberdeen and Elgin branches of Langstane Housing Association claim that promises have been broken over wage increases.
They have voted to stage the first in a series of one-day strikes on Wednesday, September 13.
Unite says Langstane staff accepted a “below inflation” pay deal last year on the understanding that they would receive a much healthier offer this year.
However, union members claim that what they have now been offered is again unsatisfactory.
Unite yesterday said “enough was enough”, and it was time to take a stand.
Regional officer, Willie Wallace, said: “We have offered to meet the company to have meaningful discussions to avoid the strikes.
“But for that to be worthwhile, there has to be a better offer on the table.
“Unfortunately the management at Langstane have not responded to our offer of further talks.”
Mr Wallace said the action had been planned in one-day instalments so as not to adversely affect the tenants who rely on the help of the striking employees
But he warned that any escalation of the dispute could create problems for those tenants.
A spokeswoman for Langstane insisted that bosses were willing to meet with union officials to prevent industrial action.
She said: “The decision by some of our staff to take strike action is very disappointing.
“We want to resolve this dispute and are willing to engage with the union.
“We have offered staff what we firmly believe is a fair and reasonable offer, which is comparable to the local housing sector.
“As a social housing provider we have to remain mindful of continuing to offer affordability to all of our tenants.”
