At-will employment is employment that either party (employer or employee) can terminate at any time, for any reason or no reason at all. Under California Labor Code 2922, all employment in the state is presumed to be "at-will" unless the parties agree otherwise or an exception to at-will employment applies. In addition to the presumption of at-will employment, many employment contracts that employers offer their employees will specify that the job is at-will and terminable at any time.
