A strike at construction company Roadstone Woods has entered its second week with no sign of a breakthrough that could end the industrial action.

Around 350 members of SIPTU and the TEEU commenced their industrial action last Monday in a dispute over bonus payments.

They have placed pickets at around 25 Roadstone locations nationwide.

The dispute centres on a 2012 cost reduction package, including an 89% cut to an annual bonus which ranged from €3,686 for salaried staff to €5,832 for craft workers, and €4,731 for general operatives.

The unions argue that as the €6m savings target has been exceeded, the bonuses should be restored with immediate effect.

However, it is understood the company wants to phase the restoration between now and 2019.

The phasing would have seen the 11% bonus restored to 25% in 2014, 30% in 2015, 50% in 2016 with full restoration on 1 January 2019.

A spokesperson for Roadstone Woods declined to comment.
