1D. For an employer, an employment agency, the commonwealth or any of its political subdivisions, by itself or its agents, to deny initial employment, reemployment, retention in employment, promotion or any benefit of employment to a person who is a member of, applies to perform, or has an obligation to perform, service in a uniformed military service of the United States, including the National Guard, on the basis of that membership, application or obligation.
1E. (a) For an employer to deny a reasonable accommodation for an employee's pregnancy or any condition related to the employee's pregnancy including, but not limited to, lactation or the need to express breast milk for a nursing child if the employee requests such an accommodation; provided, however, that an employer may deny such an accommodation if the employer can demonstrate that the accommodation would impose an undue hardship on the employer's program, enterprise or business. It shall also be an unlawful practice under this subsection to:
(i) take adverse action against an employee who requests or uses a reasonable accommodation in terms, conditions or privileges of employment including, but not limited to, failing to reinstate the employee to the original employment status or to an equivalent position with equivalent pay and accumulated seniority, retirement, fringe benefits and other applicable service credits when the need for a reasonable accommodation ceases;
(ii) deny an employment opportunity to an employee if the denial is based on the need of the employer to make a reasonable accommodation to the known conditions related to the employee's pregnancy including, but not limited to, lactation or the need to express breast milk for a nursing child;
