Question: How does an employer effectively balance corporate policies of a drug-free workplace with the legalization of marijuana becoming more common, both for recreational and prescription use? I work in HR for a commercial construction general contractor. What are your thoughts on best practices to protect the company, job-site work teams, the general public and the employees’ rights? — Mila S.

Answer: Marijuana use by employees (in or out of the workplace) is a complex issue given that many states have legalized medical and recreational weed. On one hand, the employee should be allowed to do what she wants to do on her private time. On the other hand, employers have an obligation to put safety first.
