Queensland building workers may strike if Adelaide worker Ark Tribe is jailed this week. The Construction, Forestry, Mining and Energy union says six Queensland building unions decided in May to take immediate industrial action if Mr Tribe is jailed for refusing to speak to the Australian Building and Construction Commission about a 2008 union meeting called to discuss safety issues. The ALP promised before the 2007 Federal Election, and again in 2009, to abolish the ABCC. However in February the Deputy Prime Minister, Ms Gillard, announced that a new Building Industry Inspectorate would have the same powers to force building workers to give evidence about union activity. Anyone called to give evidence before the ABCC does not have the right to silence, and can be jailed for six months for refusing to testify. The Rights on Site website has an online petition against the possible jailing of Mr Tribe.
