Carol Furlong, president of the Newfoundland and Labrador Association of Public and Private Employees, says she's disappointed more hasn't been done to implement the legislation in recent years.
Whistleblower laws protect employees who want to report wrongdoing by their employers.
It was first promised by former Premier Danny Williams in 2007, but has yet to materialize.
The New Democrats brought up the issue in the House of Assembly last week.
Justice Minister Felix Collins says he's not opposed to the legislation, but says departments which currently have whistleblower laws are experiencing problems.
Furlong says if government doesn't agree with current whistleblower legislation, then maybe it's time to look at different ideas.
