(8) For an employer, by the employer or the employer's agent, for an employment agency, by itself or its agent, or for any labor organization, by itself or its agent, to harass any employee, person seeking employment or member on the basis of sex or gender identity or expression. If an employer takes immediate corrective action in response to an employee's claim of sexual harassment, such corrective action shall not modify the conditions of employment of the employee making the claim of sexual harassment unless such employee agrees, in writing, to any modification in the conditions of employment. “Corrective action” taken by an employer, includes, but is not limited to, employee relocation, assigning an employee to a different work schedule or other substantive changes to an employee's terms and conditions of employment. Notwithstanding an employer's failure to obtain a written agreement from an employee concerning a modification in the conditions of employment, the commission may find that corrective action taken by an employer was reasonable and not of detriment to the complainant based on the evidence presented to the commission by the complainant and respondent. As used in this subdivision, “sexual harassment” means any unwelcome sexual advances or requests for sexual favors or any conduct of a sexual nature when (A) submission to such conduct is made either explicitly or implicitly a term or condition of an individual's employment, (B) submission to or rejection of such conduct by an individual is used as the basis for employment decisions affecting such individual, or (C) such conduct has the purpose or effect of substantially interfering with an individual's work performance or creating an intimidating, hostile or offensive working environment;
