Q:
Am I an at-will employee?

A:
Absent evidence to the contrary, in California all non-public employees who are not members of a union, and are not employed under a contract for a specific duration of time,  are presumed to be at-will employees.  As mentioned elsewhere on this website, however, there are numerous situations where an employee is permitted to bring a legal claim for wrongful termination or demotion against their employer even though the employee is at-will.
