A permit application by Fijian unionists for a protest march on Saturday has been declined by police.
The Fiji Trades Union Congress said no reason has been given for the application being refused.
National secretary Felix Anthony said in a statement the permit was applied for last month.
He said that during the march the unions had planned to address the ongoing harassment against workers and unionists, as well as other issues.
These include the national minimum wage, right to strike, labour law reforms, and imposition of individual contracts.
They also include issues related to Federated Airline Staff Association, and workers at the Vatukoula mine.
