My boss is constantly belittling me in front of my colleagues, making me feel embarrassed and disrespected. How can I get back at him without getting fired?

You could try expressing your dissatisfaction or frustration in constructive ways. If you don’t feel safe doing so directly, you could leave hints around the office (Post-it notes on his desk, emails to HR, etc.) or speak to other higher ups in the company who might be able to rein him in. 

Also, depending on your work environment and how your culture views confrontation, you may find it appropriate to have a meeting with your boss and express how his behavior makes you feel and why it should stop. In some workplaces this could lead to necessary change; in others it can help get the message across that belittling behavior is not acceptable without further escalating the situation.

In some cases though simply ignoring the behavior may be the best option if there are no consequences for him or none that would improve your workplace experience significantly enough compared to other potential courses of action. After all retaliation or revenge are often not worth risking a job unless circumstances involve illegal activity such as harassment or bullying that has been unchecked by management.

It can be very difficult and uncomfortable to endure such treatment. One possible way of addressing this situation is to find a respectful and diplomatic way of responding. This could involve simply redirecting theconversation by asking questions about what needs to be done or thanking him for his input and moving on. Another possible approach would be to directly address how his comments make you feel, letting him know that you would appreciate it if he spoke to you with more respect in the future. Ultimately, though, it may depend on how strong your relationship is with your boss and whether or not there are any effective ways of challenging his behavior without risking a adverse reaction.
