For Janitors covered under the King County Master Agreement: you and your family members can be covered under health insurance after you’ve worked 1040 hours, or about 6 months full time. You must sign up for coverage to begin with your employer. Premiums are 100% employer-paid; members are responsible for copays and coinsurance. For all other SEIU6 members: contact your company’s HR Dept to learn about your medical benefits.
