The Berkeley study’s second error is the omission of retiree health benefits. Private workers retire later and relatively few receive retiree health coverage. For those who do, eligibility has been tightened and premiums increased. But almost 90% of state and local governments offer retiree health benefits to employees. They generally retire in their 50s, at which point the government often pays most of their costs, including Medicare premiums and deductibles.

State actuarial reports show the annual cost of California retiree health benefits could top 8% of total compensation. Thus an accurate accounting of pension and retiree health benefits shows that public employees in California are paid about 15% more than individuals working for large private firms (accounting for age, education, etc.).

Another major benefit of public employment is job security. The Bureau of Labor Statistics reports that, on average, a private worker has about a 20% chance of being fired or laid off in a given year. In state and local government, the discharge rate is only about 6%—and several studies have found that public employees are more risk-averse than other workers, meaning they place particular value on job security. We estimate that government job security is equivalent to about a 15% increase in compensation.
