The Fiji Trades Union Congress is calling for a full investigation into anti-worker policies at Air Pacific.
This comes as the interim government farewells the chief executive, David Pflieger, in a move which the union group welcomes.
It says Mr Pflieger was instrumental in the drafting and imposition of the Essential Industries Decree, which denied workers their fundamental rights and dramatically reduced their conditions of work.
The FTUC says Mr Pflieger will go down in history as the most irresponsible and anti-worker chief executive Fiji has known.
It says under his watch Air Pacific has been reduced to a low cost carrier and there are now serious concerns about its future.
The FTUC also wants the employment of expatriate workers investigated and it calls for the airline's annual reports to be made public to ensure its continued viability.
