Probationary Period Rules in Arizona: Can You Be Fired?

Federal law provides comprehensive protection against discrimination in employment regardless of probationary status. Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e, prohibits discrimination based on race, color, religion, sex, or national origin by employers with 15 or more employees. The Age Discrimination in Employment Act (ADEA), 29 U.S.C. § 623, protects employees age 40 and older at employers with 20 or more employees. The Americans with Disabilities Act (ADA), 42 U.S.C. § 12101 et seq., requires employers with 15+ employees to provide reasonable accommodations for qualified individuals with disabilities.

The Equal Pay Act, 29 U.S.C. § 206(d), requires equal pay for equal work regardless of employee classification. Section 1981 of the Civil Rights Act, 42 U.S.C. § 1981, protects against race discrimination in contract formation and employment. Federal law also protects whistleblowers under the Whistleblower Protection Act, 49 U.S.C. § 20109 (transportation), and various industry-specific statutes. The EEOC enforces most federal anti-discrimination statutes and requires charges be filed within 180 days of the discriminatory act in non-deferral states or 300 days in deferral states. Probationary employees retain full protection under all federal laws—probationary status does not diminish these rights.

Arizona does not have a specific state statute regulating probationary periods, but Arizona Revised Statutes § 23-1501 establishes that employment is at-will unless a written contract provides otherwise. This means employers may generally terminate employees, including probationary employees, for any reason or no reason, provided the reason is not illegal. Arizona state law does, however, provide explicit protection against certain terminations even for at-will employees.

Arizona Revised Statutes § 23-1404 protects employees who report or refuse to participate in conduct they reasonably believe violates state law. This protection applies to probationary employees and cannot be waived. Similarly, Arizona Revised Statutes § 23-1405 protects employees from retaliation for jury duty, and § 23-1404.02 protects employees reporting workers' compensation violations. These protections supersede at-will employment.

Arizona does not recognize public policy exceptions to at-will employment as broadly as some states, but courts have recognized narrow exceptions protecting employees terminated for performing a legal duty (such as jury service) or reporting illegal activity. Probationary employees are entitled to the same protection against discrimination based on protected characteristics as other employees. Arizona does not have a state equal pay law stronger than the federal Equal Pay Act, and does not require employers to justify probationary periods or demonstrate legitimate reasons for termination during probation.

Unlike some states, Arizona does not require just cause for termination or impose mandatory probationary period lengths. Employers have complete discretion to set probationary terms and length. However, any probationary agreement cannot be conditioned on waiving statutory rights, such as the right to report illegal activity or the right to file a workers' compensation claim.

Arizona's at-will employment rule (A.R.S. § 23-1501) contains several important exceptions. First, an employee cannot be fired for refusing to commit an illegal act or for reporting conduct reasonably believed to violate state law under A.R.S. § 23-1404. This protection applies from day one of employment, including probationary periods. Second, employees cannot be terminated in retaliation for jury duty under A.R.S. § 23-1405. Third, employees reporting workers' compensation violations or filing workers' compensation claims are protected from retaliation under A.R.S. § 23-1404.02.

Federal anti-discrimination statutes override at-will employment. An employer cannot fire a probationary employee because of their membership in a protected class (race, color, religion, sex, national origin, age 40+, disability, genetic information, or military service). These exceptions apply regardless of probationary status or employer size thresholds; however, federal laws requiring 15+ employees (Title VII, ADA) or 20+ employees (ADEA) still apply their size thresholds.

Arizona recognizes a narrow public policy exception: termination in violation of public policy or for performing a legal duty is not protected by at-will employment. However, Arizona courts have construed this exception narrowly. Probationary employees cannot be required to waive their rights to report illegal conduct, file workers' compensation claims, or pursue legal claims as a condition of employment. Implied contracts (based on employee handbook language or employer conduct) may also limit at-will status, though probationary status does not override such contracts if they exist. Union employees and those covered by collective bargaining agreements are also exempt from pure at-will employment.

Step 1 — Document the termination and circumstances. Write down the date you were terminated, who told you, what reason (if any) was given, and the context of your employment to date. If you have a written offer letter, employment agreement, or employee handbook describing the probationary period, save it. Preserve all email communications about your probationary status, performance expectations, or termination. Keep records of your work performance, any positive feedback, and dates of any discrimination, harassment, or policy violations you reported. Take screenshots of relevant company documents if possible.

Step 2 — Consider the internal complaint process. If your employer has an HR department or internal grievance procedure, review your employee handbook to understand whether you can appeal the termination. However, Arizona employers are not required to have internal appeal procedures, and using one does not toll federal filing deadlines. Internal complaints do not waive your right to file with government agencies. If you believe the termination was discriminatory or retaliatory, document this in writing and send it to HR if you have time before filing an external complaint. This creates a paper trail but is not required.

Step 3 — File with the appropriate agency. For federal discrimination claims (race, color, religion, sex, national origin, age 40+, disability, genetic information, or retaliation for protected activity), file a charge with the EEOC. Arizona is a non-deferral state, so you have 180 days from the discriminatory act to file. File online at www.eeoc.gov/filing-charge or call the Phoenix EEOC office at 602-640-5000. Provide your name, contact information, employer name and address, date of termination, and a description of the discriminatory conduct. For retaliation for reporting law violations (A.R.S. § 23-1404), you may also file a retaliation claim with the Arizona Department of Labor. Visit azdes.gov or call 602-364-2722.

Step 4 — Understand the investigation process. After filing an EEOC charge, the agency will send the charge to your employer and request a response. The EEOC then investigates by reviewing documents and conducting interviews. Investigation typically takes 90-180 days, though complex cases take longer. You will be contacted to provide additional information or clarify details. If the EEOC finds reasonable cause to believe discrimination occurred, it will attempt conciliation (settlement negotiation) before determining whether to litigate or issue a right-to-sue letter. A right-to-sue letter allows you to file a private lawsuit in federal court.

Step 5 — Consult an employment law attorney. Given the narrow exceptions to at-will employment in Arizona, you should consult an attorney experienced in employment discrimination law before accepting a severance agreement or waiving claims. If your termination involved discrimination, retaliation, or violation of a written employment agreement, an attorney can evaluate your case. Many employment attorneys work on contingency for discrimination claims. Contact the State Bar of Arizona (602-340-7247) for attorney referrals or the Arizona Community Legal Services (602-258-3434) for low-cost assistance. An attorney can also review your probationary agreement to ensure it did not require you to waive legal rights.
