John Muller, the public servant who blew the whistle on corruption in Mpumalanga, has been hounded from his job and is now running a creche to support his family.
Muller, an Mpumalanga traffic officer who uncovered fraud in the issuing of driver's licences in the province, is just one of a growing number of whistleblowers in the public service who are being victimised, says the Democratic Party.
DP leader Tony Leon says although the public service code of conduct obliges state staff to come forward when confronted with corruption, there are no provisions to protect them from the consequences.
This has resulted in a series of cases in which whistleblowers have been hounded out of the public sector, systematically overlooked for promotion, refused transfers or suffered harassment or threats.
The DP is assembling a body of evidence on the issue - three recent cases have come to light - and this week tabled a series of parliamentary questions on the subject both to President Mbeki and to Public Service and Administration Minister Geraldine Fraser-Moleketi.
