Wisconsin courts will only impose a non-compete clause "if the restrictions imposed are reasonably necessary to protect the employer." Yes. However, the legality for the employer to take adverse steps against you – such as firing or writing to you – to refuse to sign depends on the circumstances of your case and may depend on the feasibility of the agreement the employer wishes to sign on your behalf under your state law. Contract law issues in your country can also be a factor in the application of an agreement that you are forced or threatened to sign. One of them is whether your employer is required to pay you extra money or give you another consideration, as was said in the previous question. .
