Since the COVID-19 pandemic started in 2020 and the federal government began using extraordinary measures to support workers, households and businesses, Republicans have been concerned that expanding the eligibility and generosity of unemployment benefits could slow the recovery and keep workers on the sidelines.

So why have a handful of Republican-led states now extended unemployment benefits to workers who have lost their jobs because of failing to comply with vaccine mandates, with other states considering following suit?

The answer is that some Republican politicians place fighting the culture war ahead of sound economic policy, traditional conservative principles and the best interests of their own constituents. The result will be to keep more workers on the sidelines in Arkansas, Florida, Iowa, Kansas and Tennessee at a time when labor shortages are hurting the ability of many businesses to function and are contributing to record-setting inflation — all while lengthening the duration of the pandemic.

State officials cited precisely these concerns when they stopped participating in a federal program that made unemployment benefits more generous.

It seems they may have been right — states that reduced the generosity of unemployment benefits last summer saw relatively more unemployed workers find jobs. But these states were expanding unemployment compensation with one hand while restricting it with the other, creating a new category of eligibility restricted to the unvaccinated while cutting the size of the payments and telling gig workers that they are no longer allowed to receive benefits.

Jobless benefits are a social insurance program. Employers pay into the system on behalf of workers, who ultimately bear the cost of those premiums in the form of lower wages. Workers who have lost a job through no fault of their own — for example, a mass layoff due to an economic downturn — and who are actively looking for work are eligible to collect benefits. Workers who are fired for cause or who voluntarily quit can’t receive benefits, just as someone who intentionally burns down his house can’t collect on his homeowner’s insurance policy.

Workers who don’t comply with their employer’s vaccine policy are being fired for cause. Should workers fired for not complying with corporate dress codes be granted eligibility for unemployment compensation? No. Nor should workers who choose not to follow corporate vaccine policy.

These laid-off workers are not victims. They are adults making choices about their work environment, and they should bear the responsibility for those choices, including loss of income while searching for another job.

Conservatism prizes economic liberty and argues that employers should be given broad latitude to set corporate policy, and that the terms of employment relationships should be respected. These relationships are entered into by workers and firms voluntarily.

It should be fine for employers to require their employees to be vaccinated, and fine for people to choose whether to work for employers with vaccine mandates.
