I think the $15 minimum wage applies only to Seatac airport and surrounding business workers. About 300 total will be affected. Disclaimer - I have not checked this fact thoroughly. Looks like it is an experiment. Minimum wage in WA state is already the highest in country (almost $10/hr).
FYI ..Minimum wage in Washington state is $9.19.
It will be interesting to see what happens to the $15 minimum wage. Hopefully all of the businesses will move out of SeaTac.
One of the commentators said the $15 minimum is needed because SeaTac has the highest property tax in the state. Friken liberals. “Taxes are too high. So raise the minimum wage.”
BTW - I think that the union pay scales are rated against the minimum wage (1xmin., 1.5 x min., 4 x min., etc.) So it is not just an increase in the minimum wage, but all union wages.
