Alcohol and drug testing at work: what you need to know
Summary
Host David McCullagh and employment lawyer Jennifer Cashman discuss the legal boundaries of workplace drug and alcohol testing. They explain that employers must justify testing through risk assessments, particularly in safety-critical roles, while ensuring policies are negotiated with employee representatives. The conversation covers the distinction between random and cause-based testing, the implications of zero-tolerance policies, and how addiction is treated as a disability under employment equality laws.
