Brisbane city council bus drivers will strike again on Friday afternoon in a further attempt to negotiate increased wages, improved safety and rostering changes.

Drivers will strike for four hours, between 2pm and 6pm on Friday July 28. “We will not stop campaigning until we get a fair agreement, but that will only happen when the Quirk Brisbane City Council agrees to sit down and resolve our claims,” Rail, Tram and Bus Union secretary Tom Brown told the Brisbane Times.

Approximately 115,000 regular passengers will be affected, along with 23,000 school children. The council is urging commuters to make use of rail or ferry services during the busy Friday afternoon peak-hour period (the council will also run additional CityCat services). It estimates the strike will cost taxpayers $515,000. Much of that cost is down to the one sweetener for passengers: drivers are refusing to collect fares on Thursday, the day before the strike.

Bus drivers already took strike action on two mornings last week. At the heart of the ongoing dispute with the council are driver and union concerns over shift-work regulations and workplace health and safety requirements – particularly after the murder of Manmeet Alisher while driving a council bus in Moorooka last year.
