An employer may not fire, demote, harass, or otherwise "retaliate" against an individual for filing a charge of discrimination, participating in a discrimination proceeding, or otherwise opposing discrimination. The same laws that prohibit discrimination based on race, color, sex, religion, national origin, age, and disability, as well as wage differences between men and women performing substantially equal work, also prohibit retaliation against individuals who oppose unlawful discrimination or participate in an employment discrimination proceeding.
The Wisconsin Family and Medical Leave Act requires that all employers with 50 or more permanent employees must allow employees of either sex up to six (6) weeks of leave in a calendar year for the birth or adoption of a child, up to two (2) weeks of leave in a calendar year for the care of a child, spouse, parent, domestic partner, as defined in 40.02(1) or 770.01(1), or parent of a domestic partner with a serious health condition and up to two (2) weeks of leave in a calendar year for the employee's own serious health condition.
The Bone Marrow and Organ Donation Leave Act requires that all employers with 50 or more permanent employees must allow employees up to six (6) weeks leave in a 12-month period for the purpose of serving as a bone marrow or organ donor, if the employee provides his or her employer with written verification that the employee is to serve as a bone marrow or organ donor. Leave may be taken only for the period necessary for the employee to undergo the donation procedure and to recover from the procedure.
