Workers in the motor trade are participating in Children's Hour, a fund-raising campaign where one hour's salary is donated to children's charities.
A spokesman for the campaign, which began on Monday, said there had been a positive response from workers in garages and petrol stations and taxi-drivers.
Each week a different sector is being asked to participate. Next week the construction industry is the target. Workers can donate the value of an hour's salary to the Children's Hour Account, AIB, 37 Upper O'Connell Street, Dublin 1. Credit card donations can be made by phoning 1850 311299.
