Two Christchurch tradesmen have won a case against a building firm over their exposure to asbestos on the job. Neil Silcock and Liam Milner resigned from exterior building company, Goleman Limited after they found out they'd been exposed to asbestos while doing repairs at Christchurch Hospital in 2013. The Employment Relations Authority has found Mr Silcock and Mr Milner were unjustifiably constructively dismissed, and that Goleman knew the site had tested postitive for white absestos 8 days before it informed the two workers.
