In Minnesota and throughout the United States, most forms of employment are considered “at will.” This means that an employee or employer can terminate an employment relationship at any time for any reason, so long as the reason is not illegal. When an employee sues an employer, he or she must prove that the employee was fired for an illegal reason. The illegal reason is most often discrimination, harassment, or retaliation. This can be very difficult to prove, especially when employers normally have significant resources and control of the relevant evidence. See our “illegal discrimination” section for a discussion of illegal employment practices. If you are successful at suing your former employer, your damages are often limited to lost wages. You are also required, after your termination, to make attempts to find a job of similar quality and pay. This requirement is known as “a duty to mitigate damages.” If you are able to find a job of similar quality and pay, the amount of money you have earned from this new job is factored into any lost wages you are claiming from your termination.
