A clear, updated drug and alcohol policy is the foundation of a safer, more compliant workplace. Fall is the ideal time to review your existing policy.

Whether you're managing multiple worksites, working with remote employees, or simply haven't updated your policy in years, Fastest Labs can help. Our team will work with you to revise outdated language, incorporate required testing types (like for-cause or post-accident), and design a policy that reflects your current operations.

Key considerations:
âś… Updated language around ma*****na
âś… Clear steps for reasonable suspicion
âś… Defined roles & responsibilities

Your policy isn’t just paperwork — it’s protection.
