I haven't been following closely, but I assume this must be the launch of Haven: https://en.wikipedia.org/wiki/Haven_(healthcare)

The reason is to save money by bringing a service in house, just like big companies do with all kinds of other services and products. (For example, if you're a 25-person company, you let a law firm handle your legal work. If you're a 25,000-person company, you have a staff of lawyers who work directly for you.) Insurance companies make a profit, so by doing it yourself, you can keep that money instead of giving it to them.

I don't see a reason to believe it should necessarily mean their employees miss out on anything. In theory they're at an advantage by cutting out the middleman. So in theory they could cut costs and increase benefits even if they can't improve and operate it more efficiently than current insurance companies.
