The Oregon Health Plan IS NOT FREE "as long as I'm working".
The Oregon Health Plan is Oregon's medicaid plan. EVERY STATE OFFERS MEDICAID.
Some states call it "medicaid" other states have fancy names for it like:
Oregon = Oregon Health Plan
Washington = Apple Care
California = Medi-Cal
In Oregon, you are eligible for the Oregon Health Plan if you disabled, low income, etc earning under $17,236 for a single person (not family/spouse).
California's Medi-Cal income eligibility limit is approx $16250 for a single person (not family/spouse).
Oregon's minimum wage is $11.25 per hour or $23400 annually
California's minimum wage is $12 per hour or $24960 annually
Thus, if you are working full time, you are not eligible for Oregon's Health Plan nor California's Medi-cal.
