Unexpected events frequently occur in the workplace, therefore, you need to know how to plan for them in order to respond effectively to such incidents. In the workplace, unforeseen circumstances such as illness, injury, childbirth, or family caregiving responsibilities can disrupt plans.
When employees need time off, they typically consider two very important employment-related options: short-term disability (STD) and the Family Medical Leave Act (FMLA).
Both STD and FMLA provide leave to qualified employees who need to take a certain number of days off from work. But, the two are not the same. Understanding the differences between these two options is highly important to make sure employees get the right support and benefits.
This post will discuss the specifics of STD and FMLA, including their definitions and eligibility criteria. By presenting these facts, employees can better comprehend their options for extended leave from work.

What is Short-Term Disability (STD)?
As the name implies, a short-term disability is an illness or an injury that prevents a person from working either entirely or at full capacity for some time.
Short-term disability benefits provide partial replacement of income for employees who are temporarily unable to work due to severe physical conditions like illnesses, injuries, or pregnancy-related complications.
The benefit typically covers a period ranging from a few weeks to several months. This type of disability coverage often pays a percentage of the employee’s salary during their period of disability to help them financially while they are unable to perform their work duties.
Who qualifies for short-term disability leave?
Employees need to review their employer’s short-term disability policy to understand the specific eligibility requirements and procedures for applying for short-term disability leave. Qualification for short-term disability leave typically depends on several factors, including:
- Employment Status: Employees who are covered by a short-term disability insurance policy or benefit plan are eligible to apply for short-term disability leave.
- Medical Condition: Employees must have a medical condition, illness, injury, or pregnancy-related complication that prevents them from performing their job duties.
- Duration of Disability: The medical condition must result in a temporary inability to work for a period specified by the short-term disability policy or plan. This duration varies but commonly ranges from a few days to several weeks or months.
- Waiting Period: Some short-term disability plans may require a waiting period before benefits become payable. During this waiting period, employees may use accrued sick leave, vacation time, or other paid time off.
- Certification: In most cases, employees are required to provide medical documentation or certification from a healthcare provider to prove the need for short-term disability leave.
What is the Family Medical Leave Act (FMLA)?

The Family Medical Leave Act is a federal rule to protect eligible employees’ job security when they need to take time off from work for qualified medical or family-related reasons. Unlike insurance plans, FMLA does not require any purchase; it automatically covers a significant number of employees based on their employment status.
Under FMLA, eligible employees can take unpaid leave for specific family and medical situations without risking their job. However, it is important to note that FMLA does not provide any financial compensation during the leave period, meaning that it does not provide payment for an employee’s wages.
Typically, qualified employees can take up to 12 weeks of FMLA-covered leave in a year. However, in cases where an employee needs to care for a family member who is a service member with a serious illness or injury, they may qualify for an extended period of up to 26 work weeks of leave in a year.
While FMLA leave is usually taken continuously, there are situations where employees may use intermittent leave. This allows them to divide their FMLA leave throughout the year, often by adjusting their work schedules, such as working fewer hours per day or fewer days per week, to meet their medical or family needs.
Who qualifies for the FMLA leave?
It is important to note that while FMLA provides important protections for eligible employees, it does not include paid leave. Additionally, not all employers or employees may be covered by FMLA, so it is essential to review the specific eligibility requirements and coverage details based on individual circumstances and employer policies.
To qualify for leave under the FMLA, employees must meet certain eligibility criteria, and employers must also meet specific requirements. Here are the key points:
Employee Eligibility
Below are specific cases where employees qualify for FMLA leave:
- Work Requirement: Employees must work for a covered employer, which includes private employers with 50 or more employees within a 75-mile radius, public agencies, and public or private elementary or secondary schools.
- Employment Duration: Employees must have worked for their employer for at least 12 months, which need not be consecutive, and have worked at least 1,250 hours during the 12 months immediately preceding the leave.
- Qualifying Reasons: Employees can take FMLA leave for specific qualifying reasons, such as the birth or adoption of a child, caring for a spouse, child, or parent with a serious health condition, or dealing with a serious health condition that makes them unable to perform their job duties.
Employer Requirements
Below are specific employer obligations:
- Covered Employers: As mentioned, covered employers include private employers with 50 or more employees within a 75-mile radius, public agencies, and public or private elementary or secondary schools.
- Notice and Documentation: Employers are entitled to request reasonable notice from employees who need FMLA leave and may require medical certification of the need for leave.
- Job Protection: Employers must provide job protection to employees taking FMLA leave, meaning they are generally entitled to return to their same position or an equivalent position upon their return from leave.
- Benefits Continuation: Employers must keep group health insurance coverage for employees on FMLA leave on the same terms as if they were working.
The difference between short-term disability and FMLA
The primary differences between short-term disability and the Family Medical Leave Act lie in their purpose, coverage, and benefits:
Purpose
Short-term Disability is an income replacement for employees to live on when they are unable to work due to non-work-related illness, injury, or pregnancy-related complications.
The Family Medical Leave Act allows eligible employees to take unpaid, job-protected leave for family and medical reasons, such as welcoming a new child through birth or adoption, providing care for a family member with a serious health condition, or addressing their significant health issues.

Coverage
STD coverage is provided through an employer-sponsored insurance plan or benefits program. Coverage eligibility and terms vary depending on the specific plan.
FMLA Leave is a federal law that applies to eligible employees of covered employers, including private employers with 50 or more employees, public agencies, and public or private elementary or secondary schools.
Benefits
STD provides partial income replacement during a disability period, commonly covering a percentage of the employee’s salary for a specified duration.
FMLA Leave is unpaid, meaning it does not provide direct financial compensation to employees during their time off. However, they may use accrued paid leave (such as sick leave or vacation time) or qualify for short-term disability benefits if they have such coverage.
Eligibility
Eligibility for STD benefits is determined by the terms of the employer’s insurance plan or benefits program. Employees must meet criteria related to their employment status, medical condition, and any waiting periods specified.
Eligibility for FMLA leave is determined by meeting specific criteria related to employment status, duration of employment, and hours worked. FMLA leave is available to eligible employees for qualifying family and medical reasons, regardless of whether they have short-term disability coverage.
In general, short-term disability provides income replacement for employees unable to work due to their health condition, while FMLA leave offers protected unpaid leave for specific family and medical reasons. The two can sometimes overlap when an employee’s condition qualifies for both short-term disability benefits and FMLA leave.
Final Thoughts
The differences between short-term disability and FMLA are not always very clear. However, both offer some form of protection for employees who need to take a leave from work, while each has its considerations, terms, and requirements. It is possible for a person who is ineligible for one to be qualified for the other. Knowing the key differences between the two can expedite the application process.
Short-term disability is a benefit that can be offered in advance of an event and that can cover an employee’s missed wages, while FMLA leave offers job-protected unpaid leave for specific family and medical reasons.
While STD eligibility and benefits are determined by employer-sponsored insurance plans, FMLA leave is governed by federal law and applies to eligible employees of covered employers. Both employers and employees need to understand the differences between these two options to provide appropriate support and follow the rules correctly.
It is worth mentioning that short-term disability insurance coverage and FMLA leave can be used at the same time. While an employee is out on protected leave under FMLA, the short-term disability insurance policy can help cover a portion of their expenses.
