Members of the public service union Nipsa will be balloted in September on whether they should take strike action.
Delegates at the union's annual conference in Londonderry on Wednesday voted in favour of holding the ballot.
The union said it wanted to resist "the attack on public service pensions, pay and jobs which the government and the assembly are implementing".
It said it would have a major impact on health and education, local government, housing and the Civil Service.
If members vote in favour of industrial action, it will take place in October.
