Are they the first big company to start adding insurance surcharges rather than attempting to make vaccination a requirement for employment?

Seems like it will be a fairly good motivation for anyone who hasn't decided outright that they will never get the vaccine. And it makes sense from a business perspective.

But I'm not sure this is a great precedent. I don't really want companies to have the ability to decide that certain employee health conditions (vaccinated vs unvaccinated, smoker vs non smoker, fit vs unfit) should affect the employee contribution to the insurance plan.
