SIPTU is meeting with staff of a major employer in Munster again today, after a vote for industrial action was reached at a recent ballot.
Kostal employs around 800 people in Abbeyfeale and 350 in Mallow, many of whom travel from Kerry.
The union says that the company has abolished the payment of bonuses for this year, as the company can't afford to pay them.
SIPTU Organiser Joe Kelly insists that the company hasn't engaged with the union in making its decision to cut the 1% appraisal for workers considered to have performed excellently.
He says imminent industrial action could be avoided if the company asks its employees for agreement.
