Brisbane ferry drivers will strike for two days this week in a move that will create chaos for thousands of commuters.

Ferry drivers will walk off the job early on Thursday, staging a 48-hour strike to express their anger over a lack of job security and low wages.

They also accuse ferry operator Transdev of eroding maintenance and safety standards under the contract it holds to run CityCat and CityFerry services for the Brisbane City Council.

It’s understood the strike will involve more than 130 people who work on the city’s ferry network, with the action to begin at 4am on Thursday.

“These workers have had enough after almost a year of bargaining and bully-like tactics from multinational corporation Transdev,” Jason Miners from the Maritime Union of Australia said on Tuesday.

He said many workers were being paid under award rates, and many had no sense of job security because they were employed on casual contracts.

AAP has sought comment from Transdev.
