TL;DR

The Family and Medical Leave Act (FMLA) is a US federal law enacted in 1993 that entitles eligible employees to take up to 12 weeks of unpaid, job-protected leave per year for specified family and medical reasons. Employers covered by FMLA must hold the employee's position (or an equivalent one) and maintain their health benefits during leave. For staffing agencies and employers, FMLA creates compliance obligations, temporary workforce planning needs, and specific risks around misclassification and eligibility.

Who It Covers and What It Covers

FMLA applies to private employers with 50 or more employees within 75 miles of the worksite, all public agencies, and all public and private elementary and secondary schools. An employee is eligible if they have worked for the employer for at least 12 months, have logged at least 1,250 hours in the past 12 months, and work at a location where the employer has 50 or more employees within 75 miles.

Qualifying reasons for FMLA leave include the birth, adoption, or foster placement of a child; caring for a spouse, child, or parent with a serious health condition; the employee's own serious health condition that renders them unable to perform essential job functions; and qualifying exigencies related to a family member's military service. A "serious health condition" is defined as an illness, injury, impairment, or physical or mental condition involving inpatient care or continuing treatment by a healthcare provider.

FMLA leave can be taken all at once or intermittently. Intermittent FMLA is operationally challenging for employers because it allows employees to take leave in increments as small as one hour for ongoing conditions such as chronic migraines, cancer treatment, or a family member's recurring medical needs. An employee can be absent intermittently for months without the leave appearing as a single continuous block.

Why It Matters for Recruitment

Staffing agencies are frequently asked to provide temporary coverage for employees on FMLA leave, which makes FMLA a direct revenue opportunity and a planning variable. When a client calls to say a department manager is going on 12 weeks of medical leave starting in two weeks, the agency has a defined scope of work: a qualified temporary worker for up to 84 calendar days, with an end date that may or may not be extended if leave is extended.

Coverage placements for FMLA absences require careful scoping. The replacement candidate must be able to get up to speed quickly, since there is often limited transition time. The client may not be able to share detailed information about why the permanent employee is absent, which limits the agency's ability to brief the temporary worker on the full context. Experienced staffing agencies build templated briefing processes for FMLA coverage roles to manage this consistently.

FMLA also intersects with direct hiring in ways that create risk. An employer who terminates an employee who has recently taken FMLA leave, or who disciplines an employee for using FMLA-protected leave, faces retaliation claims under the statute. Employers who rely on staffing agencies to "replace" employees on FMLA leave with permanent hires before the leave period ends face equivalent claims. Recruiters advising clients on workforce planning during FMLA absences should flag this risk clearly.

In Practice

A healthcare organization has a payroll administrator go on FMLA leave for 10 weeks following surgery. The organization contacts their staffing agency on day 3 of the absence, having initially assumed the team could absorb the workload. They cannot.

The agency places an experienced payroll specialist at a bill rate of $42 per hour. The assignment is 40 hours per week for 10 weeks: 400 hours at $42 = $16,800 in revenue for the agency. The client avoids payroll processing delays, late filings, and potential DOL penalties that could have exceeded $50,000.

The temporary worker is briefed on the payroll software (ADP Workforce Now), the pay schedule, and the client's approval workflows in a two-hour orientation on day one. The assignment runs without incident. At week 8, the client asks whether the same individual is available to stay on after the permanent employee returns, to assist with a year-end reconciliation project. The agency negotiates a two-week extension, adding $3,360 in additional revenue.
