The workers’ compensation system and the occupational health and safety system are funded by employers. The amount an employer contributes is based on the assessment rate associated with the employer’s rate group and the employer’s total assessable payroll. Assessment rates represent a dollar value that must be contributed by an employer for every $100 in assessable payroll that they declare.
Assessment rates and industry classifications are set each year by the Board of Directors.
