The Public Services Association (PSA) has hit back at Health Minister Dr Fuad Khan for his "folly" and public statements against the workers in their membership.

At a media conference yesterday, PSA's general secretary Nixon Callender pointed to several invoices, bills and cheques from both public and private health organisations and called on the Minister to investigate and explain the million-dollar documents instead of blaming workers for equipment damage at the hospital.

Nixon listed five invoices in detail where senior level management at a private hospital "allowed a member of the public" to ring up a million-dollar bill between last year and this year and questioned who authorised State funding to pay those bills.

"But they owe workers from 2008-2010, arrears of salaries to the tune of $15 million while all of this bacchanal going on. While they are fully aware that they owe you money," he said.

"We have all of them here (the invoices) so they cannot run, they cannot hide," he said.

He said the industrial relations crisis at the Northwest Central Regional Health Authority (NCRHA) appeared to have "evolved into one where a drill has become the main focus".

"The Public Private Partnership Initiative concept and workers grievances have now faded into the background as the source of discomfort being experienced by the workers and patients at the institution," he said.

"The question must be asked, what is the Minister trying to hide. Why is it we have all this mismanagement, the wastage of money," he said.

PSA first vice president Christopher Joefield, yesterday added that Khan was obviously aware that there were more issues at hand than just the drill. He said the workers were being penalised for their protest action and he was reliably informed that legal action was being leveraged against protesting workers.
