Overview of Employee Leaves

MIT provides paid leaves to most employees when they are unable to work due to injury or illness.

This page describes leaves for non-faculty employees. See this page for details on faculty leaves for medical and family care, including maternity and parental leave.

MIT's leaves as described below comply with the Family Medical Leave Act (FMLA), a federal law providing unpaid family and medical leave with job protection, as well as the Massachusetts Paid Family Medical Leave Act (PFMLA), a state law that provides pay at a State Rate, along with job protection for family and medical leaves for employees. The FMLA and the PFMLA run concurrently. See background information on the PFMLA.

Sick/Medical Leaves

For benefits-eligible staff

  • Benefits-eligible staff may use accrued sick time when they cannot work because of: minor illness or injury, medical appointments, and serious health conditions. (See the definition of a serious health condition below.)
    • Accrued sick time is paid at 100% pay
  • Sick time is accrued on a monthly basis for all staff
    • At hire, employees are credited with 20 days of sick time
    • After 1 year of service, sick time accrues at the rate of 1 day per completed month of service, like vacation time
    • Sick time accruals are capped at 132 days for salaried staff and for all new hires
      • Higher caps apply to support staff hired on or before December 31, 2020
  • For serious health conditions, staff have a choice to use either their accrued sick time (100% pay) or Serious Illness Reduced Pay (SIRP; 80% of pay)
    • SIRP replaces Extended Sick Leave for hourly paid staff
    • SIRP also is available for salaried staff
    • Salaried staff hired before January 1, 2021 are also eligible for Transitional Salaried Serious Illness Pay at 100%. See Employment Policy Manual Section 4.3.3.3.
  • Staff giving birth may use their accrued sick time or SIRP for:
    • Prenatal care appointments
    • Time they are unable to work due to pregnancy
    • Childbirth, and recovery from childbirth
      • The usual period for childbirth and recovery is presumed to be 8 weeks; where needed and supported by medical documentation, a longer medical leave may be granted

All leaves under the PFMLA (for sick leave and/or family leave) are capped at 26 weeks, in the aggregate, in a 52-week period (called a Benefit Year).

  • For leaves due to a staff member’s serious health condition, the 26 week cap includes time paid under MIT’s sick time and SIRP policies
    • Example: Employee who uses 10 weeks of sick time for a serious health condition may take up to 16 weeks of SIRP for that same condition where medically necessary (26 week total).

  • Up to 20 weeks paid at the state formula rate (see below under Definitions) for serious health conditions only
    • If any accrued sick time is used for a serious health condition, that time counts towards the 20 weeks

    • Prenatal care appointments
    • Time they are unable to work due to pregnancy
    • Childbirth, and to recover from childbirth

Family Leaves

For benefits-eligible staff

MIT provides three types of family leaves for benefits-eligible staff:

1. For parents to bond with a new child (consisting of Paid Parental Leave and/or Bonding Leave)

2. To care for a family member with a serious health condition

3. For certain reasons when a family member is or was in the Armed Forces

For bonding with a new child

    • Paid Parental Leave is paid at 100% of regular pay
  • Following Paid Parental Leave, new parents may take up to 8 weeks of Bonding Leave
    • This leave is paid at the state formula rate (see below under Definitions) and must also be taken within 1 year of the child’s birth, adoption, or placement
    • Note: the 20 days/4 weeks of Paid Parental Leave counts towards the 12 weeks of Bonding Leave provided under the PFMLA.
To care for a family member with a serious health condition
  • A staff member may use up to 5 days of their accrued sick time as "sick family" time, paid at 100%
  • Sick family time is limited to 5 days per anniversary year
  • After those 5 days, the staff member may take up to 11 weeks of family leave paid at the state formula rate (see below under Definitions)
  • Alternatively, if the staff member has used all their sick family leave, or if they choose not to use their 5 days of sick family leave at 100% pay, they may be paid for up to 12 weeks at the state formula rate
Leaves related to family members currently or formerly in the Armed Forces
  • Qualifying exigencies: 12 weeks
    • Qualifying exigencies are needs arising out of an employee’s family member’s active duty or service (or call or order to active duty), including providing for care of the military member’s child or other family member, making financial or legal arrangements for the military member, and spending time with the military member during a rest and recuperation period or following return from deployment.

Maternity and Parental Leaves

The information below applies to benefits-eligible MIT faculty, staff, and postdocs (associates and fellows) as well as non-benefits eligible staff. It does not apply to graduate students. Graduate students should consult the parental accommodation policies on the Office of Graduate Education website.

Maternity Leave

Leaves for employees giving birth (“maternity leave”) fall under MIT’s sick leave policies. Maternity leaves cover time that an employee cannot work due to:

  • Childbirth
  • Recovery from childbirth

MIT generally assumes a period of incapacity for eight weeks for childbirth and recovery; that period may be longer if supported by appropriate medical documentation.

Benefits-eligible staff may use their accrued sick time for maternity leave, or may use SIRP. Salaried staff employed as of December 31, 2020 may use the Transitional Salaried Serious Illness Pay as provided in Section 4.3.3.3.

Benefits-eligible staff may follow their maternity leave with Parental Leave (see next section). Combined, those leaves may look like this:

Maternity leave for non-benefits eligible staff working in Massachusetts is paid via any accrued sick time under the Massachusetts Earned sick time law or at the state formula rate (see below under Definitions).

Paid Parental Leave and Bonding Leave

Benefits-eligible new parents – birth parents, adoptive parents, and foster parents – are generally eligible for MIT’s Paid Parental Leave followed by Bonding Leave, for a total of 12 weeks.

MIT Paid Parental Leave is 20 days, and is paid 100% of usual pay. Bonding Leave is 8 additional weeks, and is paid at the state formula rate (see below under Definitions).

Non-benefits eligible new parents working in Massachusetts are also eligible for Bonding Leave for up to 12 weeks, paid at the state formula rate.

Paid Parental Leave and Bonding Leave must be completed within 12 months after the child’s birth, adoption, or foster placement.

Human Resources has developed a chart with steps for new parents to help guide them through the leave process. Download it below.

 Action Steps for New Parents

Topping Off Leave Pay

In certain circumstances, employees may supplement (or “top off”) their pay with accrued time while on an approved PFML leave. At MIT these include leaves for an employee’s own serious health condition or to care for a seriously ill family member. Learn more about topping off and see how to request to top off your leave pay.

Intermittent Leaves

Both continuous and intermittent leaves are available. An intermittent leave may be taken for a serious health condition which requires periodic treatment by a healthcare provider for an employee’s own serious health condition, for a serious health condition of a family member, or for certain reasons for family members who are or have been in the Armed Forces. Leave increments may be as short as an hour or as long as several weeks at a time.

Definitions

Serious Health Condition

The PFMLA defines a serious health condition as a physical or mental condition that prevents one from doing their job either because they are unable to, or because they need time to get treated or recover from treatment. A Serious Health Condition is an illness, injury, impairment, or physical or mental condition that involves (a) inpatient care in a hospital, hospice, or residential medical facility; or (b) continuing treatment by a Healthcare Provider.

The term Serious Health Condition includes any period of incapacity due to pregnancy or for prenatal care, and for childbirth and recovery from childbirth ("maternity leave").

See information on the medical documentation that is required for leaves related to serious health conditions.

State Formula Rate

When leaves are paid at the state formula rate, the payment is calculated based on a formula applied to the staff member's actual past wages. In 2024, the maximum weekly benefit rate is $1,149.90.

The Massachusetts Department of Family and Medical Leave (which oversees the PFMLA) has an online calculator that allows employees to estimate the amount of gross pay they will be paid under the state formula, based on the employee’s earnings over the prior four quarters. This calculator is a helpful tool for employees looking to see what their rate of pay would be for any MIT medical or family leave that is paid at the state formula rate. Because the calculator only provides an estimate, the final gross amount may differ.

Deductions will be taken from the gross pay at the state formula rate for items like taxes, your share of health premiums, and other deductions regularly taken from your paycheck. Deductions that are based on a percentage of pay, like a 401(k) contribution, will be reduced if your paycheck is reduced because you are paid at the state formula rate.

Family Member

The federal and state laws governing sick and family leaves – including the Family and Medical Leave Act (FMLA), the Massachusetts Earned sick time law, and the Massachusetts Paid Family and Medical Leave Act (PFMLA) – have different definitions of the term "family member." MIT’s general sick and family leave policies use the PFMLA definition, which is also the most broad.  However, MIT’s specific policies on the FMLA (Employment Policy Manual Section 4.8.3)  and Earned sick time (Employment Policy Manual Section 4.3.8) use the definitions required by those laws.  The chart below contains the different definitions of "family member."

Health Care Provider

The federal and state laws governing sick and family leaves – including the Family and Medical Leave Act (FMLA), the Massachusetts Earned sick time law, and the Massachusetts Paid Family and Medical Leave Act (PFMLA) – also have different definitions of  the term "health care provider." As with the term "family member," MIT’s sick leave policies (sick time and SIRP) use the PFMLA definition, which is the broadest. However, MIT’s specific policies on the FMLA (Employment Policy Manual Section 4.8.3)  and Earned sick time (Employment Policy Manual Section 4.3.8) use the definitions required by those laws.  The list below contains the different definitions of "health care provider."

 In all cases, the professional (doctor, nurse practitioner etc.) must be licensed by the state in which the individual practices.

  • Doctor of medicine or doctor of osteopathy
  • Dentist
  • Podiatrist
  • Clinical psychologist
  • Optometrist
  • Nurse practitioner
  • Nurse midwife
  • Clinical social worker
  • Physician assistant
  • Chiropractor, but only for treatment consisting of manual manipulation of the spine to correct a subluxation as demonstrated by X-ray to exist) for subluxation of the spine
  • Certain Christian Science Practitioners listed with the First Church of Christ, Scientist
  • Health care provider listed above who practices in a country other than the United States, who is authorized to practice in accordance with the law of that country, and who is performing within the scope of his or her practice as defined under such law.
  • For leaves under the FMLA only, any health care provider from whom an employer or the employer’s group health plan’s benefits manager will accept certification of the existence of a serious health condition to substantiate a claim for benefits.

Note that cosmetic surgery is not covered by MIT’s leave laws nor by the PFMLA.
