Drug testing at work is now routine for thousands of safety critical workers. Employment contracts have evolved to enable employers to routinely screen for drugs pre-employment candidates, after workplace accidents and incidents, and on a random basis.
Drug testing at work has become more commonplace as rates of social drug and alcohol use have increased. Increasing social drug use is recognised to impact negatively on workplace productivity and safety. Increasing awareness of employers duty of care withing the workplace with the need to ensure a safe working environment at all times justifies indentifying employers attending the workplace under the influence of drugs and/or alcohol.
Where the safety argument works for train drivers and fork lift truck operative, the productivity argument increasingly works for all other employees and increasingly managers at all levels.
