@RkXLyzG-3uku Thank you very informative and you explained the very strong advantages.
@RkXLyzG-3cbg But even so, the poster said " one is able to meet with HR and the Union Rep to get whatever questions answered," I suspect if we met with HR they would be naturally on the side of the company, where as the union rep is standing behind the worker.
Kaiser in California is a very very strong healthcare system and union and the nurses, doctors, staff are very protected in their jobs
