Frequently asked questions
What is workers compensation insurance?
Workers compensation (WorkCover in Australia, WSIB/WCB in Canada, Employers' Liability in the UK) covers medical costs and lost wages for employees injured or made ill while at work. In the US, it is mandatory in almost every state. The employer pays the premium; the insurer covers claims. In India, the Employees' State Insurance Corporation (ESIC) scheme serves workers earning up to ₹21,000/month, funded by employer and employee contributions.
How are workers compensation rates determined?
Rates are set per $100 (or equivalent) of payroll and vary primarily by industry classification code. High-risk industries like construction carry rates of $5–$8 per $100 of payroll in the US, while clerical office workers cost as little as $0.35. Employers with good claims histories may qualify for experience-modification discounts; frequent claimants pay higher rates.
What is an experience modification factor?
After three or more years of coverage, US and Canadian insurers apply an experience modification (e-mod) factor to your base rate. A clean claims history yields a mod below 1.0 (cheaper); frequent or severe claims push it above 1.0 (more expensive). A business with a 0.80 mod pays 20% less than the base rate.
Are independent contractors covered by workers compensation?
Generally no — workers compensation covers employees, not independent contractors. However, if a contractor is misclassified, the hiring company may be liable. Some states and countries are tightening rules on contractor classification, so it is worth reviewing your workforce structure with an insurance broker or labour lawyer.

How workers compensation premiums are calculated
Workers compensation premiums are calculated by multiplying your total payroll by a rate that reflects the injury risk of your industry. In the US, rates are expressed per $100 of payroll and range from $0.35 for office workers to $8.00 for construction workers. A construction firm with $500,000 in annual payroll would pay an estimated $40,000 per year, while an equivalent office firm would pay only $1,750. Canada and Australia use similar per-$100 rate structures; the UK uses a percentage of payroll through its Employers' Liability Insurance framework.
Reducing your workers compensation costs
The most effective way to reduce premiums is to prevent workplace injuries. Implement a robust safety programme, provide regular training, and investigate every incident — even near misses. Return-to-work programmes that help injured employees transition back into light duties can reduce claim severity and duration, lowering your experience modification factor. Some insurers offer premium credits for drug-free workplaces, safety certifications, and formal safety management systems.
