  1. For an employer, by himself or his agent, because of the race, color, religious creed, national origin, sex, gender identity, sexual orientation, which shall not include persons whose sexual orientation involves minor children as the sex object, genetic information, pregnancy or a condition related to said pregnancy including, but not limited to, lactation or the need to express breast milk for a nursing child, ancestry or status as a veteran of any individual to refuse to hire or employ or to bar or to discharge from employment such individual or to discriminate against such individual in compensation or in terms, conditions or privileges of employment, unless based upon a bona fide occupational qualification.

  1A. It shall be unlawful discriminatory practice for an employer to impose upon an individual as a condition of obtaining or retaining employment any terms or conditions, compliance with which would require such individual to violate, or forego the practice of, his creed or religion as required by that creed or religion including but not limited to the observance of any particular day or days or any portion thereof as a sabbath or holy day and the employer shall make reasonable accommodation to the religious needs of such individual. No individual who has given notice as hereinafter provided shall be required to remain at his place of employment during any day or days or portion thereof that, as a requirement of his religion, he observes as his sabbath or other holy day, including a reasonable time prior and subsequent thereto for travel between his place of employment and his home, provided, however, that any employee intending to be absent from work when so required by his or her creed or religion shall notify his or her employer not less than ten days in advance of each absence, and that any such absence from work shall, wherever practicable in the judgment of the employer, be made up by an equivalent amount of time at some other mutually convenient time. Nothing under this subsection shall be deemed to require an employer to compensate an employee for such absence. "Reasonable Accommodation”, as used in this subsection shall mean such accommodation to an employee’s or prospective employee’s religious observance or practice as shall not cause undue hardship in the conduct of the employer’s business. The employee shall have the burden of proof as to the required practice of his creed or religion. As used in this subsection, the words "creed or religion” mean any sincerely held religious beliefs, without regard to whether such beliefs are approved, espoused, prescribed or required by an established church or other religious institution or organization.

  Undue hardship, as used herein, shall include the inability of an employer to provide services which are required by and in compliance with all federal and state laws, including regulations or tariffs promulgated or required by any regulatory agency having jurisdiction over such services or where the health or safety of the public would be unduly compromised by the absence of such employee or employees, or where the employee’s presence is indispensable to the orderly transaction of business and his or her work cannot be performed by another employee of substantially similar qualifications during the period of absence, or where the employee’s presence is needed to alleviate an emergency situation. The employer shall have the burden of proof to show undue hardship.

  1B. For an employer in the private sector, by himself or his agent, because of the age of any individual, to refuse to hire or employ or to bar or to discharge from employment such individual, or to discriminate against such individual in compensation or in terms, conditions or privileges of employment, unless based upon a bona fide occupational qualification.

  1C. For the commonwealth or any of its political subdivisions, by itself or its agent, because of the age of any individual, to refuse to hire or employ or to bar or discharge from employment such individual in compensation or in terms, conditions or privileges of employment unless pursuant to any other general or special law.

  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;

  (iii) require an employee affected by pregnancy, or require said employee affected by a condition related to the pregnancy, including, but not limited to, lactation or the need to express breast milk for a nursing child, to accept an accommodation that the employee chooses not to accept, if that accommodation is unnecessary to enable the employee to perform the essential functions of the job;

  (iv) require an employee to take a leave if another reasonable accommodation may be provided for 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, without undue hardship on the employer’s program, enterprise or business;

  (v) refuse to hire a person who is pregnant because of the pregnancy or because of a condition related to the person’s pregnancy, including, but not limited to, lactation or the need to express breast milk for a nursing child; provided, however, that the person is capable of performing the essential functions of the position with a reasonable accommodation and that reasonable accommodation would not impose an undue hardship, demonstrated by the employer, on the employer’s program, enterprise or business.

  (b) As used in this subsection, the following words shall have the following meanings unless the context clearly requires otherwise:

  "Reasonable accommodation”, may include, but shall not be limited to: (i) more frequent or longer paid or unpaid breaks; (ii) time off to attend to a pregnancy complication or recover from childbirth with or without pay; (iii) acquisition or modification of equipment or seating; (iv) temporary transfer to a less strenuous or hazardous position; (v) job restructuring; (vi) light duty; (vii) private non-bathroom space for expressing breast milk; (viii) assistance with manual labor; or (ix) a modified work schedule; provided, however, that an employer shall not be required to discharge or transfer an employee with more seniority or promote an employee who is not able to perform the essential functions of the job with or without a reasonable accommodation.

  "Undue hardship”, an action requiring significant difficulty or expense; provided, however, that the employer shall have the burden of proving undue hardship; provided further, that in making a determination of undue hardship, the following factors shall be considered: (i) the nature and cost of the needed accommodation; (ii) the overall financial resources of the employer; (iii) the overall size of the business of the employer with respect to the number of employees and the number, type and location of its facilities; and (iv) the effect on expenses and resources or any other impact of the accommodation on the employer’s program, enterprise or business.

  (c) Upon request for an accommodation from the employee or prospective employee capable of performing the essential functions of the position involved, the employee or prospective employee and the employer shall engage in a timely, good faith and interactive process to determine an effective, reasonable accommodation to enable the employee or prospective employee to perform the essential functions of the employee’s job or the position to which the prospective employee has applied. An employer may require that documentation about the need for a reasonable accommodation come from an appropriate health care or rehabilitation professional; provided, however, that an employer shall not require documentation from an appropriate health care or rehabilitation professional for the following accommodations: (i) more frequent restroom, food or water breaks; (ii) seating; (iii) limits on lifting more than 20 pounds; and (iv) private non-bathroom space for expressing breast milk. An "appropriate health care or rehabilitation professional” shall include, but shall not be limited to, a medical doctor, including a psychiatrist, a psychologist, a nurse practitioner, a physician assistant, a psychiatric clinical nurse specialist, a physical therapist, an occupational therapist, a speech therapist, a vocational rehabilitation specialist, a midwife, a lactation consultant or another licensed mental health professional authorized to perform specified mental health services. An employer may require documentation for an extension of the accommodation beyond the originally agreed to accommodation.

  (d) Written notice of the right to be free from discrimination in relation to pregnancy or a condition related to the employee’s pregnancy including, but not limited to, lactation or the need to express breast milk for a nursing child, including the right to reasonable accommodations for conditions related to pregnancy pursuant to this subsection, shall be distributed by an employer to its employees. The notice shall be provided in a handbook, pamphlet or other means of notice to all employees including, but not limited to: (i) new employees at or prior to the commencement of employment; and (ii) an employee who notifies the employer of a pregnancy or an employee who notifies the employer of a condition related to the employee’s pregnancy including, but not limited to, lactation or the need to express breast milk for a nursing child not more than 10 days after such notification.

  (e) Subject to appropriation, the commission shall develop courses of instruction and conduct public education efforts as necessary to inform employers, employees and employment agencies about the rights and responsibilities established under this subsection not more than 180 days after the appropriation.

  (f) This subsection shall not be construed to preempt, limit, diminish or otherwise affect any other law relating to sex discrimination or pregnancy or in any way diminish the coverage for pregnancy or a condition related to pregnancy including, but not limited to, lactation or the need to express breast milk for a nursing child under section 105D of chapter 149.

  (1) a refusal to permit or to make, at the expense of the handicapped person, reasonable modification of existing premises occupied or to be occupied by such person if such modification is necessary to afford such person full enjoyment of such premises; provided, however, that, in the case of publicly assisted housing, multiple dwelling housing consisting of ten or more units, or contiguously located housing consisting of ten or more units, reasonable modification shall be at the expense of the owner or other person having the right of ownership; provided, further, that, in the case of public ownership of such housing units the cost of such reasonable modification shall be subject to appropriation; and provided, further, that, in the case of a rental, the landlord may, where the modification to be paid for by the handicapped person will materially alter the marketability of the housing, condition permission for a modification on the tenant agreeing to restore or pay for the cost of restoring, the interior of the premises to the condition that existed prior to such modification, reasonable wear and tear excepted;

  Notwithstanding any other provisions of this subsection, an accommodation or modification which is paid for by the owner or other person having the right of ownership is not considered to be reasonable if it would impose an undue hardship upon the owner or other person having the right of ownership and shall therefore not be required. Factors to be considered shall include, but not be limited to, the nature and cost of the accommodation or modification needed, the extent to which the accommodation or modification would materially alter the marketability of the housing, the overall size of the housing business of the owner or other person having the right of ownership, including but not limited to, the number and type of housing units, size of budget and available assets, and the ability of the owner or other person having the right of ownership to recover the cost of the accommodation or modification through a federal tax deduction.

  In the event a wheelchair accessible unit becomes or will become vacant, the owner or other person having the right of ownership shall give timely notice to a person who has, within the previous twelve months, notified the owner or person having the right of ownership that such person is in need of a unit which is wheelchair accessible, and the owner or other person having the right of ownership shall give at least fifteen days notice of the vacancy to the Massachusetts rehabilitation commission, which shall maintain a central registry of accessible apartment housing under the provisions of section seventy-nine of chapter six. During such fifteen day notice period, the owner or other person having the right of ownership may lease or agree to lease the unit only if it is to be occupied by a person who is in need of wheelchair accessibility.

  Notwithstanding any general or special law, by-law or ordinance to the contrary, there shall not be established or imposed a rent or other charge for such handicap-accessible housing which is higher than the rent or other charge for comparable nonaccessible housing of the owner or other person having the right of ownership.

  Notwithstanding the foregoing provisions of this section, it shall not be an unlawful employment practice for any person, employer, labor organization or employment agency to inquire of an applicant for employment or membership as to whether or not he or she is a veteran or a citizen.

  Notwithstanding the provisions of any general or special law nothing herein shall be construed to bar any religious or denominational institution or organization, or any organization operated for charitable or educational purposes, which is operated, supervised or controlled by or in connection with a religious organization, from limiting admission to or giving preference to persons of the same religion or denomination or from taking any action with respect to matters of employment, discipline, faith, internal organization, or ecclesiastical rule, custom, or law which are calculated by such organization to promote the religious principles for which it is established or maintained.

  Notwithstanding the foregoing provisions of this section, (a) every employer, every employment agency, including the division of employment and training, and every labor organization shall make and keep such records relating to race, color or national origin as the commission may prescribe from time to time by rule or regulation, after public hearing, as reasonably necessary for the purpose of showing compliance with the requirements of this chapter, and (b) every employer and labor organization may keep and maintain such records and make such reports as may from time to time be necessary to comply, or show compliance with, any executive order issued by the President of the United States or any rules or regulations issued thereunder prescribing fair employment practices for contractors and subcontractors under contract with the United States, or, if not subject to such order, in the manner prescribed therein and subject to the jurisdiction of the commission. Such requirements as the commission may, by rule or regulation, prescribe for the making and keeping of records under clause (a) shall impose no greater burden or requirement on the employer, employment agency or labor organization subject thereto, than the comparable requirements which could be prescribed by Federal rule or regulation so long as no such requirements have in fact been prescribed, or which have in fact been prescribed for an employer, employment agency or labor organization under the authority of the Civil Rights Act of 1964, from time to time amended. This paragraph shall apply only to employers who on each working day in each of twenty or more calendar weeks in the annual period ending with each date set forth below, employed more employees than the number set forth beside such date, and to labor organizations which have more members on each such working day during such period.
