California Overtime Laws: Can You Refuse to Work Overtime? 

A woman is sleeping at a desk with her head on her work desk, perhaps from overtime working.

You're not alone if you've ever been asked to stay late after your shift or come in on your day off. Overtime is a common part of many jobs, but what happens if you say no? Can your employer fire you for refusing to work overtime in California? 


The short answer? Yes, but there are a few exceptions that could apply to you. 


Let’s break down what the law says and what your rights are as an employee in California. 


California Is an At-Will Employment State 


First things first: California follows the at-will employment rule. That means your employer can fire you for almost any reason, or no reason at all—unless it’s illegal (like firing you because of your race, gender, religion, disability, or for engaging in protected activity). 


So, can your boss fire you just because you refused to work overtime? In most cases, yes. But context matters.

When Refusing to Work Overtime Can Get You Fired  


Under California labor law, employer’s are allowed to schedule employees to work overtime. If you refuse, they can discipline or even fire you, if you don’t have a legal or contractual reason to decline. 


According to the California Department of Industrial Relations (DIR): 


“An employer may discipline or terminate an employee who refuses to work scheduled overtime.” 


This applies even if you’ve already worked a full day or a full week. As long as you are paid correctly for the overtime work and the scheduled overtime is not excessive, you cannot refuse to work overtime without a legitimate reason. 


When Refusing Overtime Might Be Protected 


Here’s where it gets more nuanced. There are situations where you might have a right to say no without risking your job: 


 

  1. You’re Covered by a Union Contract:  If you’re in a union or have an employment contract that limits how much overtime you can be required to work, your employer must follow those terms. Check your collective bargaining agreement (CBA) or employment contract. 
  2. Overtime Poses a Health or Safety Risk:  If excessive overtime would create a dangerous situation, like working with heavy machinery while exhausted, you may have the right to refuse under Cal/OSHA safety laws.  You also have the right to report unsafe conditions without retaliation. 
  3. Medical or Disability-Related Reasons:  If you have a medical condition that limits how long you can work, and it's recognized under the Americans with Disabilities Act (ADA) or California’s Fair Employment and Housing Act (FEHA), you may be able to request a reasonable accommodation, like avoiding overtime. If your employer fires you for requesting this, it could be considered disability discrimination.
  4. Religious Beliefs:  If overtime conflicts with your sincerely held religious beliefs (e.g., working on the Sabbath), you can request a religious accommodation. Employers must reasonably accommodate religious practices unless it creates an undue hardship. 

Exempt vs. Non-Exempt Employees: Know the Difference 


Not all employees are treated the same under overtime laws. Here's an example to help understand the difference


 

  • Non-exempt employees (usually hourly workers) are entitled to overtime pay: 
  • 1.5x pay after 8 hours/day or 40 hours/week 
  • 2x pay after 12 hours/day or 7 days in a row 
  • Exempt employees (like some salaried professionals and managers) aren’t entitled to overtime pay and are often expected to work longer hours. 

 

If you're a non-exempt employee and refusing paid overtime, your employer may view this as you refusing to fulfill your job duties. If you're an exempt employee, your options may be limited, but it’s still worth discussing with HR or an employment lawyer. 


What You Can Do If You're Being Pressured to Work Overtime  


Here are some practical steps to protect yourself: 

 

  • Review your employee handbook: Some companies have specific policies about overtime and scheduling. 
  • Talk to HR or your supervisor: If you have a legitimate reason for refusing, explain it professionally and in writing. 
  • Document everything: If you’re fired or disciplined, having a paper trail helps protect you legally. 

 

Consult an employment attorney: If you feel your rights are being violated (especially if discrimination, retaliation, or a protected reason is involved), talking to a lawyer can make all the difference. 


The Bottom Line 


Yes, you can be fired for refusing to work overtime in California, but there are exceptions. If you’re protected by a union contract, health and safety rules, or discrimination laws, you may have legal grounds to say no without fear of being disciplined or terminated.

California has wrapped up another busy legislative session, and Governor Gavin Newsom has approved a wide range of new workplace laws that employers will need to prepare for in 2026 and beyond. These measures touch nearly every corner of employment compliance, from labor rights and pay transparency to leave rules, recordkeeping, and restrictions on certain contract terms. Below are a few key changes that stand out. 1. Expanded Labor Rights for Workers and Gig Drivers A new law (AB 288) strengthens workers’ rights to organize and gives the Public Employment Relations Board the power to step in when federal labor protections fall short. Another measure (AB 1340) creates a framework allowing certain gig-economy drivers to unionize and negotiate industry-wide standards without changing their independent contractor status. 2. Broader Pay Data and Equal Pay Requirements Under SB 464, employers with 100 or more workers will face stricter pay-data reporting rules, including penalties for failing to file and expanded job-category reporting starting in 2027. SB 642 also updates California’s Equal Pay Act by clarifying what counts as wages, including bonuses, equity, and benefits, and setting a six-year limit for filing claims. 3. New Limits on Repayment Agreements AB 692 restricts employers from requiring workers to repay training costs or other debts when they leave a job, unless very specific exceptions apply (such as accredited programs or prorated hiring bonuses). Most repayment-based contract terms tied to separation will no longer be allowed. Read more in the National Law Review, HERE .
