Employers are not legally required to offer severance during layoffs, but many choose to do so to maintain goodwill and ease the transition for their former employees. If you are offered a severance agreement, remember that you don't have to sign it right away.
It makes no difference how long you've been with a company so yes, it's legal to lay off any and everyone without severance. The exceptions: a union agreement requiring severance, a personal contract calling for a severance. This is usually only for executives and ``key'' people.
Severance is never a requirement of any employer unless you have a signed employment agreement stating otherwise, or, it is a written policy of the company.
You and your employer must follow certain legal formalities for a severance agreement to be enforceable. You must ensure that the agreement is in writing and that your employer has signed it. Sometimes, you might also need a witness or have it notarized. Failing to adhere to these formalities can void the agreement.
Lack of Voluntary Consent: Under California law, a severance agreement can be considered valid and enforceable only if the parties entered into it voluntarily. If your consent was obtained through coercion, duress, or fraud, the agreement will be deemed invalid.
The primary consequence of rejecting a severance offer is forfeiting the guaranteed compensation and benefits outlined in the severance agreement.
