Report: Four-in-10 California Workers’ Comp Claims from Workers with Less Than a Year of Tenure

April 1, 2024

Roughly four-in-10 workers’ compensation claims come from workers with less than one year of tenure, a new report from the Workers’ Compensation Insurance Rating Bureau of California shows.

The report shows 40% of workers’ comp claims come from workers with less than one year of tenure, and those workers are more than twice as likely to have a claim relative to the statewide average.

The report, Impacts of Employee Tenure on Workers’ Compensation Claim Frequency in California, is on Research section of the WCIRB website.

Other report findings include:

  • Injuries differ among length of tenure: Workers with less than a year of tenure are more likely to have fall, struck or cut injuries, while longer-tenured workers tend to have more strain injuries.
  • Workers with longer tenure tend to have a higher share of cumulative trauma indemnity claims.
  • After adjusting for age, the average incurred losses on indemnity claims, valued at approximately 18 months from policy inception, are higher for longer-tenured injured workers.
