A Queens man, his daughter and two union leaders pleaded guilty yesterday to swindling more than 300 workers out of about $600,000 in wages.

Merkourios Angeliades and his daughter, Irena, paid employees at M.A. Angeliades $20 an hour in cash for overtime, weekend or holiday shifts for working construction at subway stations.

But they reported the proper, higher wages and pocketed the difference.

They pleaded guilty to falsifying business records in Bronx Supreme Court.

Anthony Graham and Eduardo Visone, both with Local 703, pleaded guilty to charges of falsifying business records.
