The Workers’ Compensation Insurance Rating Bureau of California (WCIRB) has released a new report, Impacts of Employee Tenure on Workers’ Compensation Claim Frequency in California. The full report is available in the Research section of the WCIRB website and at the following link: 

• Impacts of Employee Tenure on Workers’ Compensation Claim Frequency in California 

Highlights of the report include: 

• About 40 percent of workers’ compensation claims come from workers with less than one year of tenure, and they are more than twice as likely to have a claim relative to the statewide average. 
• Injuries differ among length of tenure too: 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.
