The answer to this question is "yes and no." Indeed, Arizona is one of a number of "right to work" states. This has nothing to do with whether an employer can fire an employee for a particular reason. It simply means that Arizona has a state law forbidding an employer from agreeing that union membership will be required of its employees. People often confuse the term "right to work" with "at will" employment. Arizona, along with every other state except Montana, recognizes the presumption that people who are working in the private sector for an indeterminate period can be terminated at the will of the employer, with or without cause.
