If you are an employee at will without an employment contract, the answer is yes. In these tough economic times such reductions are becoming more and more common.
Good luck to you.

I agree. If you have no contract and are employed at will, they can reduce your pay or terminate you, and your recourse is to find another job.
I am not licensed to practice law in Washington so the foregoing should not be taken as legal advice, but simply as educational information intended to be helpful. If you need legal advice, please consult a lawyer who holds Washington licensure.
I'm adding my answer to the list already posted because I AM licensed to practice in the State of Washington, so you need not wonder whether a different rule might apply here.
Unfortunately, the employer can legally cut your pay going forward. Here are some additional things that might be helpful to know:
1) The employer cannot cut your pay retroactively (for work that you have already done.)
2) If your rate of pay is established by contract (either a collective bargaining agreement or an individual contract), the pay cannot be cut unless provided for in the contract.
3) Minimum wage in Washington State is $8.55/hour.
4) If your compensation,or your hours, are reduced by 25% or more, you will qualify for unemployment compensation if you resign.
Reductions in pay are happening quite a lot. Sometimes this is because employers are trying to avoid laying anyone off, and sometimes employers are just taking advantage of the market. There is no way to tell which is happening in any given case, and no recourse if the motivation turns out to be opportunism.
