Construction unionists have been temporarily banned from striking outside building sites managed by a major contractor in Brisbane.

The building industry watchdog successfully brought an injunction against the CFMEU in Federal Court on Thursday preventing it from holding a month-long spate of strikes and work stoppages outside sites run by Hutchinson Builders.

The Fair Work Building Commission alleges several CFMEU officials targeted nine of Hutchinson’s sites and disrupted work 15 times since late August, including the $360m Skytower project and the $120 million Newstead Central apartment block.

It’s alleged in some instances the union disrupted crucial works like concrete pouring by holding two-hour “information meetings” without notice that workers are allowed to attend as part of their enterprise bargaining agreement.

FWBC director Nigel Hadgkiss said the ongoing and disruptive nature of the stoppages had prompted the need for urgent court intervention.

According to statements filed in court, the CFMEU’s dispute with the contractor stems from it not consulting with the union and using non-EBA subcontractors.

The injunction expires at 4.15pm on October 11.
