Mental Health in the Workplace: A Comprehensive Employer and Employee Guide
The Scale of the Challenge
Mental health conditions are the leading cause of disability worldwide (WHO, 2022). In employment:
- 1 in 6 workers experience a mental health condition at any given time (Mind/CIPD, 2022)
- Mental health conditions cost UK employers £56 billion annually (Deloitte, 2022) — up from £45 billion in 2019
- In the US, depression alone causes an estimated 200 million lost workdays per year, costing employers $17–$44 billion (CDC)
- 75% of mental health conditions begin before age 24, meaning most employees with mental health conditions developed them before entering the workforce
