Washington Employment Contract Review
Reviewing a job offer or employment agreement in Washington? The clauses that matter most, the non-compete, invention assignment, and arbitration, are governed by Washington law, and the same clause can be enforceable in one state and void in the next. Here is how Washington treats each, and what ClauseAudit checks before you sign.
Non-compete in Washington
Limited, enforceable only in narrow cases
Typical enforceable duration: 18 months
Are non-competes enforceable in Washington?
Enforceable only above a high, inflation-adjusted earnings threshold, with advance disclosure, and capped at 18 months.
Governing law: Washington RCW 49.62.
Whatever the label in your contract, Washington courts look at whether the restriction is reasonable in duration, geography, and scope. A nationwide, multi-year, whole-industry ban is far more likely to be narrowed or struck down than a narrow one.
Who owns what you invent in Washington?
Washington has a statute protecting inventions you create on your own time, with your own resources, unrelated to your employer's business, similar to California Labor Code §2870. A blanket assignment of "all inventions" that ignores this carve-out may be unenforceable as to your personal projects. Look for the statutory exclusion in your agreement.
Arbitration and class-action waivers in Washington
Washington is among the states that have acted to limit forced arbitration of certain employment claims, though many clauses remain enforceable under federal law. Check whether the arbitration clause is mutual and whether it waives your right to join a class action.

Washington employment contract FAQ
Are non-competes enforceable in Washington?
In Washington, non-competes are enforceable only in limited circumstances under Washington RCW 49.62. Enforceable only above a high, inflation-adjusted earnings threshold, with advance disclosure, and capped at 18 months.
Can my Washington employer own inventions I make on my own time?
Washington is one of a handful of states with a statute protecting inventions employees make on their own time, with their own resources, unrelated to the employer's business, similar to California Labor Code §2870. A blanket IP-assignment clause that ignores that carve-out may be unenforceable as to those personal inventions.
Do I have to sign a mandatory arbitration agreement in Washington?
Washington is among the states that have moved to limit forced arbitration for certain employment claims. Even so, many arbitration clauses are enforceable under federal law, read whether it is mutual and whether it waives class actions before you sign.
Are non-competes enforceable in Washington?
Washington is one of 9 jurisdictions that allow non-competes only in restricted circumstances. Enforceable only above a high, inflation-adjusted earnings threshold, with advance disclosure, and capped at 18 months. See RCW §§ 49.62.005-49.62.900.
How long can a non-compete last in Washington?
Courts in Washington have treated 18 months as the outer edge of what is typically reasonable for an employee. Duration is only one factor: geography and the scope of restricted activity are weighed alongside it, and a term that is reasonable for a senior employee may not be for a junior one.
What if I work in Washington but my employer is in another state?
It matters, because Washington's neighbours do not all treat non-competes the same way: Idaho (generally enforceable). Which state's law applies turns on the governing-law and venue clauses in your contract and on where the work is actually performed, so those two clauses are worth reading closely before you sign.
If a Washington non-compete is too broad, does it get narrowed or thrown out?
Courts may rewrite an overbroad restriction to something reasonable. That cuts against you: an employer has little to lose by drafting wide, because a court can pare the clause back rather than discard it. Negotiating the wording before signing matters more here than in states where an overbroad clause simply fails.
What else should I check in a Washington employment contract?
Beyond the non-compete: how invention assignment is worded and whether it reaches work done on your own time; whether disputes go to arbitration and whether class actions are waived; whether notice periods are symmetrical between you and the employer; and how any equity vests, including what happens if you leave before a cliff.
