Edwards was separated from her job following widespread criticism, including from the then Opposition Jamaica Labour Party (JLP) and environmental groups, over her handling of a massive fire at the Riverton City disposal site in St Andrew.
In its ruling which was handed down last week, the IDT ordered that Edwards be paid three years’ basic pay for the period February 2015 to February 26 this year.
It said Edwards should also be paid in lieu of vacation leave she would have earned during the period.
Her contract was not renewed after smoke from the massive fire at the waste disposal site blanketed large sections of the Corporate Area and parts of St Catherine for more than a week.
Under pressure, the then NSWMA board did not renew Edwards’ contract, citing non-performance on her part.
