Kentucky workers’ compensation benefits are calculated from the injured worker’s average weekly wage, and a second job can raise that number. Under KRS 342.140(5), when an employee works under concurrent contracts with two or more employers and the employer liable for the case knew of the other employment before the injury, wages from all the employers count toward the average weekly wage. A second job also creates risk after the injury, because paid work while receiving disability benefits can reduce or end those benefits.

Kentucky Workers’ Compensation Coverage

Kentucky workers’ compensation is governed by KRS Chapter 342. Under KRS 342.630, any employer in Kentucky with one or more employees subject to the chapter, other than one engaged solely in agriculture, must comply with it, and the same rule covers the state, counties, cities, and school districts. Coverage applies to injuries and occupational diseases arising out of and in the course of employment. Fault does not decide coverage: a worker whose own mistake contributed to the injury is still covered. The hub page on Kentucky workers’ compensation coverage and benefits sets out the full list by statute.

Benefits available under KRS Chapter 342 include:

  • Medical benefits for necessary treatment of the work injury.
  • Temporary total disability benefits, paid at 66 2/3% of the average weekly wage within the state limits set by KRS 342.730, while the worker is temporarily unable to work.
  • Permanent partial disability benefits, based on the impairment rating and other factors.
  • Permanent total disability benefits, for workers who cannot return to any work.
  • Death benefits for surviving dependents.

Second Job Wages in the Average Weekly Wage

An injured worker’s wage replacement benefit is calculated from the average weekly wage. When the concurrent employment rule in KRS 342.140(5) applies, the calculation includes wages from every employer, including the job where the injury happened.

The difference can be substantial. When both jobs count, the wage base for temporary total disability includes the second job, and when only the primary job counts, the calculation starts from a smaller number. The statute conditions the rule on the liable employer’s knowledge of the other employment before the injury, so that knowledge is a fact worth establishing early.

Average Weekly Wage Computation Under KRS 342.140

KRS 342.140(1) sets the method by how the wages were fixed. A weekly wage is the average weekly wage. A monthly wage is multiplied by twelve and divided by fifty-two, and a yearly wage is divided by fifty-two. When wages were fixed by the day, hour, or output, the average weekly wage is the wage most favorable to the employee, computed by dividing by thirteen the wages, not including overtime or premium pay, earned in the first, second, third, or fourth period of thirteen consecutive calendar weeks in the fifty-two weeks before the injury.

An employee with less than thirteen calendar weeks at the employer is computed as if employed the full thirteen weeks, when work was available to other employees in a similar occupation. In exclusively seasonal occupations, the average weekly wage is one-fiftieth of the total wages the employee earned from all occupations in the twelve calendar months before the injury. Under KRS 342.140(6), wages also include the value of board, rent, housing, lodging, and fuel or similar advantage from the employer, and gratuities from others to the extent reported for income tax purposes.

Income Reporting Requirements

All income from all sources has to be reported when applying for workers’ compensation benefits. That includes:

  • Part-time jobs at other employers.
  • Gig work and app-based income, such as rideshare, delivery, and freelance work.
  • Self-employment income.
  • Under-the-table cash payments.

KRS 342.335 prohibits knowingly filing, or permitting to be filed, a false or fraudulent claim for compensation, and procuring or receiving payments of compensation through fraud, deceit, or misrepresentation when the recipient is not lawfully entitled to them. Insurers use surveillance, bank records, and social media to detect unreported work. Accurate reporting protects the case, and the full reported number is the one the benefit calculation should use.

Working While Receiving Temporary Total Disability

Holding a second job while receiving temporary total disability benefits puts those benefits at risk. Kentucky’s workers’ compensation system replaces wages lost because of a work injury, and temporary total disability is paid because the worker cannot work during recovery.

Insurer Investigations of Work Activity

Workers’ compensation insurers hire investigators and use social media monitoring, public records, and income database checks. When they find evidence of work activity during a temporary total disability period, they:

  • Argue the worker is not totally disabled from the injury.
  • Seek termination of temporary total disability benefits.
  • Use the evidence to question the worker’s credibility on the extent of the injuries in any dispute or hearing.
  • Refer the case for a fraud investigation.

Paid Work That Affects Benefits

The risk reaches past physical labor. Performing any paid services, even light administrative or remote work, during a temporary total disability period can trigger these consequences. The insurer’s argument is simple: a worker who can do that job can do some form of work, so temporary total disability benefits should be reduced or eliminated.

Some limited activity is permitted, such as medically supervised rehabilitation or approved light duty. Under KRS 342.730(7), temporary total disability benefits paid while the employee works a light-duty or alternative job position are offset by the employee’s gross income minus applicable taxes from that work. Any secondary income or work activity during a case should be reviewed with a workers’ compensation attorney before it starts.

New Employment During a Workers’ Compensation Case

Taking a new job while receiving temporary total disability benefits from the original employer’s insurer raises the same problem as working a second job. Temporary total disability compensates the worker while the injury keeps them from working, and wages earned elsewhere undercut that basis.

Permanent partial disability works differently. Many injured workers return to some form of employment after reaching maximum medical improvement, and permanent partial disability benefits can continue. Under KRS 342.730(1)(c), a worker who returns to work at a weekly wage equal to or greater than the pre-injury average weekly wage receives the standard permanent partial disability benefit while that employment lasts, and the weekly benefit doubles during any period when that employment stops. A worker who lacks the physical capacity to return to the type of work performed at the time of injury can receive three times the standard amount. How new income interacts with these benefits depends on the facts of each case.

Other Income That Offsets Benefits

Two offsets in KRS 342.730 apply whether or not a second job is involved. Under subsection (5), income benefits for temporary total and permanent total disability are offset by unemployment insurance benefits paid for unemployment during the period of total disability. Under subsection (6), income benefits are offset by payments from an exclusively employer-funded disability plan, disability retirement plan, sickness and accident plan, or salary continuation that extends income benefits for the same disability, except where the employer-funded plan contains an internal offset provision for workers’ compensation benefits that is inconsistent with the statute.

Third-Party Injury Claims

Workers’ compensation pays two-thirds of the average weekly wage and covers medical bills, but it does not pay for pain and suffering, the full extent of lost future earnings, or emotional distress. When a third party’s negligence caused or contributed to a work injury, the worker can have a separate personal injury case in addition to the workers’ compensation case.

Common examples include a delivery driver injured when a car runs a red light, a construction worker hurt by a defective piece of equipment, and an office worker injured when a third-party contractor’s negligence causes a fall. Third-party claims run parallel to workers’ compensation, and the workers’ compensation carrier may hold a subrogation interest in the recovery. The firm’s page on construction accident cases shows how this plays out on job sites, and workers’ compensation claim denials covers what happens when the insurer refuses the case. On-the-job crashes with another driver follow the car accident case rules for the third-party side.

Could Your Second Job Change Your Benefits?

Wages from a second job can raise the average weekly wage used to calculate workers’ compensation benefits, and returning to work while on temporary total disability raises its own questions. Sam Aguiar Injury Lawyers reviews whether an on-the-job injury also supports a third-party case, such as a crash with another driver during work hours.

Frequently Asked Questions

1Does second job income count in Kentucky workers’ comp benefits?+
It can. Under KRS 342.140(5), when an employee works under concurrent contracts with two or more employers and the employer liable for the case knew of the other employment before the injury, wages from all the employers count toward the average weekly wage. A calculation based only on the injury job understates the benefit in that situation.
2Can someone work a second job while receiving workers’ comp benefits?+
Income from work during temporary total disability can reduce the benefit. KRS 342.730(7) offsets the temporary total disability benefits otherwise payable for the period the employee has returned to a light-duty or other alternative job position by an amount equal to the employee’s gross income minus applicable taxes during that work. KRS 342.0011(11)(a) defines temporary total disability as the condition of an employee who has not reached maximum medical improvement from an injury and has not reached a level of improvement that would permit a return to employment.
3What if the second job paid cash under the table?+
All income has to be disclosed, including cash income and informal work arrangements. KRS 342.335 prohibits receiving workers’ compensation benefits through fraud, deceit, or misrepresentation. Insurers use bank records, tax filings, witnesses, and investigators to detect unreported income.
4Can a separate personal injury case be filed in addition to workers’ comp?+
Yes, when a third party such as another driver, a contractor, an equipment manufacturer, or a property owner caused or contributed to the injury. That case can include pain and suffering, full lost wages, and other damages workers’ compensation does not cover. The two cases run separately, and the workers’ compensation carrier may hold a subrogation interest in the third-party recovery.
