Workplace violence and harassment training must be provided when a worker is hired, and any time there are changes to workplace policies, procedures, job roles, or risk factors. Some jurisdictions also recommend regular refresher training, typically every 1 to 3 years, to ensure workers stay informed.

As an industry best practice, it is not advisable to exceed 3 years without retaining workers.

Employers are responsible for keeping training current and relevant. If there’s a workplace incident, near miss, or updated legislation, retraining may also be required.
