Hi Chris, we have had a D&A policy on site for approx. 5 years, covers pre employment, random, post incident and reasonable cause, we made the policy fit the business so safety sensitive covers the whole site and all employees when introduced, which made it easier to roll out and the control and management is simple, rather than breaking it down by areas or tasks, this also includes all management this presents a fair system also to the employees. We have seen reduction in H&S incidents, and culture and morale has improved, employees appreciate the seriousness we take on drugs in the workplace and this shows through commitment to make the workplace drug free. The challenge we are facing is the harder drugs that are used and the fact they are less easy to detect, which takes more than a test, you also need leaders educated on drug use and awareness on the floor to ensure issues are dealt with promptly.
