I am surprised by this ruling as I think the unions had a valid point, all the works in a union shop benefit from what the union negotiates, unless non-union people are settling for less.

The ruling specifically addresses the issue you mention.Here is the ruling

You do understand that the SEIU was forcing people who were acting as personal assistants providing home care to their relatives to pay union dues. These people are essentially private contractors paid by the state of Illinois. What is fair about that?

So the union was just claiming these people as members just because, that there were not legitimate union workers? That does make it different.
