A result is expected today of a Communications Workers' Union (CWU) ballot on industrial action at An Post.
The outcome of the ballot will not be known until 2pm. However, the union said last night that there had been "very strong" support for industrial action, up to and including a strike, which would involve a total stoppage of postal deliveries.
The union opened the ballot on October 5th over its claim that An Post has failed to honour national pay agreements.
It has accused the company of failing to pay workers and pensioners cost-of-living increases due under the Sustaining Progress national agreement.
The union has rejected a Labour Court ruling that linked pay increases due under the agreement to cost savings that would affect 4,500 delivery workers.
If the workers vote for industrial action, the CWU will notify the company later today if strike action is to follow. The union will give An Post 14 days' notice before its members stop work.
