A new pay agreement has been agreed at Bausch and Lomb Waterford.
It's believed that the agreement was passed 788-155 in favour of yes.
A statement from Bausch and Lomb stated:
"We welcome the outcome of the ballot of SIPTU members regarding a new pay agreement. This positive result will bring certainty to our facility at Waterford allowing us to focus on delivering our products to our many customers around the globe. When given the opportunity to vote on the proposal, the result shows the commitment our employees have to both the short and longer-term future of the Waterford site."
Staff at Bausch and Lomb in Waterford were to vote on the new pay deal in a bid to avert further strike action at the plant.
Terms of the agreement include pay increases of almost 10 per cent and restoration of bonuses.
Siptu members recently staged work stoppages at the contact lens maker to force a resolution after talks broke down at the Workplace Relations Commission (WRC).
Both sides agreed to return to the WRC last week and received a proposal from the commission, which the union's thousand-strong workforce then balloted on.
