Election or Rejection of Coverage Form: Michigan Coverage Exclusion and Inclusion Forms and Instructions – This link will take you to a Michigan Workers Compensation website page. Once there scroll down to Form WC-337 Notice of Exclusion and Form WC-338 Notice to Terminate Exclusion.

Notes About Forms: Be sure to check with your insurance company for additional forms they may use.

Contractors: If one company hires another company to come in and do some work for it, the second company is ordinarily an “independent contractor” and not an employee of the first company. Sometimes, however, a company hires one person to come in and perform a specific job and disputes arise as to whether or not that person is an employee or an independent contractor. Section 161(1)(n) of the Act states that if the worker does not maintain a separate business, does not hold himself or herself out to and render service to the public, and does not employ other workers, the worker will be considered an employee.

Special Notes: There are a few classes of workers who are covered by federal laws and are not covered by the Workers’ Disability Compensation Act of Michigan. Employees of the federal government (such as postal workers, employees at a veterans administration hospital, or members of the armed forces) are covered by federal laws. People who work on interstate railroads are covered by the Federal Employers Liability Act. Seamen on navigable waters are covered by the Merchant Marine Act of 1920, and people loading and unloading vessels are covered by the Longshoremen’s and Harbor Workers’ Compensation Act. Virtually all other workers and employers are subject to Michigan’s law. Agricultural employees are exempt under certain special circumstances. An agricultural employer, however, may voluntarily cover its workers. Section 161(2) of the Act provides that certain family members of an employer may be excluded from the Act.

Michigan Statute About Subrogation
Michigan Workers Working In Other States; Other States Workers Working In Michigan, Extraterritorial, Reciprocity and Non-Compliance:  If Michigan workers are working temporarily in another state, then workers compensation coverage for that worker is governed by the extraterritorial provisions found in Michigan statutes. When allowed, extraterritorial provisions allow benefits for an injured worker to apply as if the worker was in their primary state. Not all states provide Extraterritorial Provisions. It’s reciprocity that governs coverage for a worker from another state who is working temporarily in Michigan. If a worker received benefits under the laws of another state or jurisdiction the amount recovered under the law of the other state, whether paid or to be paid in future installments, shall be credited against the benefits payable under the Michigan act. This is commonly known as a credit or offset. Compliance of workers compensation laws varies from state to state and it is important for an employer with workers performing duties in other states to be aware of the specific state rules that govern their coverage. We’ve provided the below general information about extraterritorial and reciprocity as a basic guide. Please contact your state authority with your specific questions concerning this topic!
