Yes, a US employer can fire one of its workers without notice if they want to. That’s because most US employees work under an ‘at will’ arrangement rather than performing their role under an employment contract. US workers are free to resign without notice, and equally, US employers can terminate a role without notice.

However, there are some exceptions to this doctrine. US employers are not permitted to fire a US worker, with or without notice, based on the following reasons:

• Race
• Sex
• Age
• Pregnancy
• Religion or creed
• Sexual orientation
• National origin or ancestry
• Physical or mental disability
• Veteran status
