WASA backs down, Watson Duke keeps job and gets no-pay leave extension PDP leader Watson Duke. - Public Services Association (PSA) president Watson Duke will not be fired from the Water and Sewerage Authority (WASA) as the utility's CEO Lennox Sealy has retracted warning letters sent to Duke and also granted him an extension of his no-pay leave for another four years, in order for him to attend to PSA duties. In a letter sent to Duke on Thursday, Sealy withdrew warning letters sent on March 9 and April 14, calling on him to account for his absence from WASA for some 11 years – on no-pay leave – to focus on his role at the PSA.
