An unsigned agreement with your employer can be enforceable in California. A missing signature does not automatically erase a promise about your pay or other employment terms. You’ll need to show what your employer promised and that you both agreed to it. Some agreements also require signatures, so it helps to speak with an employment lawyer about your specific situation.

A binding agreement requires clear terms that both you and your employer accepted. You must also exchange something of value, such as your work in return for compensation. For example, your manager promises you a $1,000 bonus for completing a specific project by Friday. You accept and finish the project on time. Your employer may still owe you that bonus, although the paperwork was never signed. Compare that with a manager saying they might offer bonuses if business improves. A vague statement like that is harder to enforce because it does not explain what you must do or how much you will receive.
You and your employer can show that you accepted an agreement by following its terms. For example, an unsigned offer letter promises $30 an hour. You start working, and your employer pays you that amount. Your work and those payments can help establish an agreement about your hourly rate.
If your employer disputes another promise in the letter, such as a bonus after six months, keep the letter and any messages explaining the bonus requirements. Records showing that you met those requirements can help support your request for payment.
Some employment arrangements have additional requirements. For example:
The last situation often arises when paperwork is still being negotiated. If emails say that management approval or signatures are required before a deal becomes final, the unsigned document may remain a proposal.
Keep anything that helps show what your employer promised and that you accepted the offer. Examples include:
Check for electronic signatures, too. Your employer may have signed electronically by typing a name or approving the document online. The surrounding messages can help show that both sides agreed to handle the paperwork electronically and that the approval was intended as a signature.
Ask for a written explanation of the denied payment or disputed term. Keep the response with your records and note who made the original promise.
