Almost €100,000 in compensation has been paid to staff working in Paddy Power bookmaker shops following the company's concession that they had been denied rest breaks.
92 separate cases have passed through the Workplace Relations Commission, according to trade union Mandate, which represents 300 workers at the firm.
A final decision was issued last Friday by the WRC.
Each of the workers who took a case will get compensation of between €700 and €1,000 each.
"Hopefully Paddy Power and all companies ensure their workers get their basic entitlements in the future," said Robert McNamara, Mandate Divisional Organiser in a statement.
He added that the company has confirmed it is will not appeal the decisions and has paid over the money.
Flutter Entertainment, the parent company of Paddy Power, said it had no comment to make on the development.
The union said it has written to the firm seeking a meeting to discuss a pay increase for members.
It also wants to talk to the company about a sick pay scheme, safe staffing levels and Sunday premium rates of pay.
In a statement Mandate said it will be left with no alternative other than to seek an intervention in the Workplace Relations Commission, if the company continues to refuse to engage and allow staff be represented by a union.
