Although the Michigan courts generally adhere to a presumption of at-will employment, there are a number of statutory and recognized common law exceptions to this rule.
Court attendance. Employers may not discipline or discharge employees for absences resulting from a summons to jury duty or, in the case of an employee who has been a victim of a crime, for absences resulting from a summons from the prosecutor to appear as a witness in court (MI Comp. Laws Sec. 600.1346 andSec. 780.762).
Garnishment. Employers may not discipline or discharge employees because their wages are being garnished or their income is being withheld for child support payments (MI Comp. Laws Sec. 600.4015andSec. 552.623).
Genetic tests. It is illegal to require an individual to submit to a genetic test or to provide genetic information as a condition of employment or promotion (MI Comp. Laws Sec. 37.1202).
Lie detector tests. Michigan employers may not request or require that an employee or applicant take or submit to a lie detector test as a condition of employment, promotion, or change in employment status (MI Comp. Laws Sec. 37.203).
Military membership. It is unlawful to discharge or discipline an employee for being a member of the U.S. or state military, naval forces, or militia (MI Comp. Laws Sec. 32.271 andSec. 32.272).
