When Michael Williamson resigned last summer as head of Australia's Health Services Union, his problems were only beginning. This past April 8, police in Sydney accused the embattled former labor leader with diverting about $600,000 in union funds to his own purposes over a more than three-year period. The charges follow 20 charges lodged against him early last October related to embezzlement, fraud and obstructing a police investigation. Williamson and several other persons were arrested. In all, the union under his leadership allegedly made at least $20 million in questionable, if not illegal payments to vendors without proper documentation. The case also serves as an example of why mixing union business and national politics, in any country, is an invitation to corruption.
