There has to be a way. Found this on the paid leave site.

“Some employees, however, may choose to apply for an exemption from WA Cares coverage. It’s their responsibility to apply, and—if approved—to notify and give their employer(s) a copy of their approval letter from Employment Security Department (ESD). Once approved, exemptions are permanent and employees can never opt back in.”

Employers can opt out by showing they have a voluntary plan.

I have enough sick days banked up to cover short term leave and will never use this. It’s just income tax.
