The Mississippi Employers Notice of Controversial is a document used by employers in the state of Mississippi to dispute a claim for unemployment insurance benefits. It is typically sent to the Mississippi Department of Employment Security (MODES) when an employer contests the eligibility or entitlement of a worker to receive unemployment benefits. There are two types of Mississippi Employers Notice of Controversial: the "Voluntary Controversial" and the "Controversial by Default." The "Voluntary Controversial" is sent when an employer voluntarily agrees to contest a claim for unemployment benefits, while the "Controversial by Default" is sent when an employer fails to respond to a Notice of Claim for unemployment benefits. Both types of Notice of Controversial must include details about the employer's decision to contest the claim, a detailed explanation of the employer's position, and the employer's contact information.
