Workers' Compensation

By TapTalent Editorial TeamUpdated

Definition

Workers' compensation is state-mandated insurance that pays medical costs and partial lost wages to employees injured or made ill by their job, regardless of who was at fault. In exchange, employees generally give up the right to sue the employer for that injury. Almost every US employer with employees must carry it.

Also called: Workers comp, Workers' comp insurance, Workman's comp, Workers compensation insurance

Formula

Annual premium = (Payroll ÷ 100) × Class code rate × Experience modification factor

Payroll
Estimated annual gross wages for employees in the class, audited at year end. Overtime premium is often excluded.
Class code rate
The rate per $100 of payroll for the job classification, set by the state rating bureau or insurer. Clerical work is cheap; roofing is expensive.
Experience modification factor
Often called the EMR or e-mod. 1.00 is average; below 1.00 means fewer or smaller claims than peers, above 1.00 means more.

Worked example

A distribution center has $4,200,000 of warehouse payroll at a class rate of $3.10 and $600,000 of clerical payroll at $0.18. Its e-mod is 1.15. Premium = (42,000 × 3.10 + 6,000 × 0.18) × 1.15 = (130,200 + 1,080) × 1.15 = $150,972. Bringing the e-mod down to 0.90 would cut that to $118,152, a saving of about $32,800 a year.

What workers' comp covers

Workers' comp is a no-fault system. If an injury or illness arises out of and in the course of employment, it is generally covered even if the employee made a mistake. Benefits typically include:

  • Medical care: treatment, prescriptions, physical therapy and travel to appointments, with no deductible or copay for the employee in most states.
  • Temporary disability: partial wage replacement while the employee cannot work, commonly about two-thirds of average weekly wage up to a state maximum, after a short waiting period.
  • Permanent disability: payments for lasting impairment, calculated by state formula.
  • Vocational rehabilitation in some states.
  • Death benefits to dependents.

Coverage includes repetitive stress injuries, such as carpal tunnel syndrome in data entry and contact center work, and some occupational illnesses. It generally does not cover injuries during a normal commute, from horseplay, or caused by intoxication, though the details vary by state.

Who must carry it

Each state runs its own system, so there is no single federal rule. Most states require coverage as soon as you have one employee; a few set thresholds of three to five employees, and some exempt certain farm or domestic workers. Texas is the main exception: private employers can choose not to carry it, but non-subscribers lose important legal defenses if an employee sues.

Employers usually buy a policy from a private insurer, buy from a state fund, or self-insure with state approval. Four states (North Dakota, Ohio, Washington and Wyoming) run monopolistic state funds, so employers there must buy through the state. Federal employees and some industries, such as longshore and maritime workers, are covered by separate federal programs.

Coverage follows where the employee works. A company with work-from-home agents in 15 states needs coverage that applies in each of those states.

How premiums work

Premium is driven by three things: how much payroll you have, the risk of the work, and your own claims history. Each job is assigned a class code (in most states, codes maintained by NCCI), and each code has a rate per $100 of payroll. Office clerical work might run well under $0.50; warehouse, healthcare and construction codes can run several dollars.

The experience modification factor compares your past three years of claims, typically excluding the most recent year, with what is expected for an employer of your size and class mix. Frequency hurts more than severity in most formulas, so ten small claims can raise the e-mod more than one large one.

Workers' comp is a meaningful part of the burden rate staffing firms and finance teams use to price labor. For a temp agency placing light industrial workers, comp costs often decide whether an account is profitable.

How a workers' comp claim works

  1. Employee reports the injury to a supervisor. States set reporting deadlines, often 30 days or less, but early reporting is always better.
  2. Employer gets care for the employee and provides the claim form required by the state.
  3. Employer reports to the insurer, usually within a few days. Late reporting drives up costs.
  4. Insurer investigates and accepts or denies the claim.
  5. Benefits are paid and the case is managed until the employee returns to work or the claim closes.

Separately, OSHA requires many employers to record work-related injuries and illnesses on the OSHA 300 log and to report severe injuries within short deadlines. A workers' comp claim and an OSHA recordable are related but not the same thing.

Employers may not retaliate against an employee for filing a claim. Comp leave can also run alongside FMLA and ADA obligations, so coordinate with whoever manages leave of absence cases.

Controlling workers' comp costs

  • Return-to-work programs. Light or modified duty gets people back sooner and cuts indemnity costs. A contact center can often place a warehouse-injured employee in a seated role; plan these jobs before you need them.
  • Correct class codes. Misclassified payroll is common. A clerical employee coded as warehouse costs many times more.
  • Ergonomics. Adjustable chairs, headsets and screen setups for agents; lift training and equipment for warehouses.
  • Safety onboarding for new hires. In many industries a large share of injuries happen in the first year. In a hiring wave, that first-year group can be a third of your workforce.
  • Report claims fast and stay in touch with the injured employee. Employees who feel ignored are more likely to hire an attorney.

Workers' comp and staffing

When workers come through a staffing agency, the agency usually carries comp as the employer of record and builds the cost into its markup. The client still controls the worksite, so its safety practices drive the agency's claims. Contracts should say who handles safety training, injury reporting and return-to-work. Workers' comp laws vary a lot by state; get advice for each state where you have workers.

Frequently asked questions

What does workers comp insurance cover?

Medical treatment, partial wage replacement while the employee cannot work, payments for permanent impairment, sometimes retraining, and death benefits for dependents, for injuries and illnesses caused by work.

How is a workers comp premium calculated?

Payroll divided by 100, times the rate for each job's class code, times the employer's experience modification factor, plus any state surcharges or discounts.

Can an employee sue an employer instead of filing workers comp?

Generally no. Workers' comp is the exclusive remedy for most workplace injuries. Exceptions exist in some states for intentional harm or when the employer failed to carry required coverage.

Are remote employees covered by workers comp?

Yes, if the injury arises from work, such as a fall while carrying work equipment during working hours. Proving work-relatedness is harder at home, which is why clear remote work policies help.

Do independent contractors need workers comp?

The hiring company usually does not cover true contractors, but if a worker is misclassified, the company can be liable for unpaid premiums and benefits.
