Public sector workers across Northern Ireland are to stage a 24-hour strike in a dispute over budget cuts and jobs.
Members of the GMB union working in education, the civil service, transport, the Rivers Agency, Forestry Service and Environment Agency will walk out on March 13.
Other unions are believed to be considering joining the strike.
The GMB warned that 20,000 jobs could be axed and claimed that savings from redundancies could be used to pay for a tax cut for big business.
Regional officer Alan Perry said: "Thousands of jobs and millions of pounds will be taken from the economy in both private and public sectors - thousands will join the dole queues."
