When is a complaint not accepted?

If your complaint is already being investigated by someone else (eg a solicitor, union or another government department)
If you have lodged an unfair dismissal application, the NSW IR will not investigate your complaint until the unfair dismissal claim has been finalised
The NSW IR is unlikely to investigate any complaint where allegations of criminal activity remain unresolved
If your employer is incorporated, they are likely to be covered by the federal industrial relations system. You can complain directly to the Fair Work Online
If your former employer is in liquidation. You should proceed with your claim through the appointed liquidator, the Workplace Ombudsman or the General Employee Entitlements and Redundancy Scheme.
