Employee returning to the workplace after USERRA military leave

If an employee tells you they've been called to military duty, you may suddenly be facing questions most employers rarely encounter. For example, do you have to hold the employee's job? Is the leave paid? Can you ask for military orders? What happens to health insurance, seniority, and the employee's position when they return?

The Uniformed Services Employment and Reemployment Rights Act (USERRA) provides important protections for service members who leave civilian employment for qualifying military service. But USERRA law isn't necessarily the only law that applies. State military leave laws, employment agreements, and workplace policies may create additional obligations.

Here's what you should know about managing USERRA military leave, from your employee's initial notice through benefits and reemployment.

What Is the USERRA Law?

USERRA is a federal law that protects the employment and reemployment rights of people who leave civilian employment to perform qualifying uniformed service. It applies to private employers and state and local governments, regardless of employer size.

This law prohibits discrimination based on past, present, or future military service or obligations, and prohibits retaliation against employees who exercise their USERRA rights, assist someone else in exercising those rights, or participate in a USERRA investigation. In addition, it establishes important leave-related benefits and reemployment protections for eligible service members.

What Types of Service Qualify for USERRA Military Leave?

USERRA may cover both voluntary and involuntary service in the uniformed services. Depending on the circumstances, qualifying service can include active duty, active duty for training, inactive duty training, certain National Guard and Reserve service, fitness-for-service examinations, funeral honors duty and certain National Disaster Medical System service.

Does USERRA Cover State Active Duty?

Since January 5, 2021, USERRA has covered certain National Guard service performed under state authority, including qualifying state active duty lasting 14 days or more when it supports a national emergency declared by the President or a major disaster declared under federal law.

Do Military Leave Laws Vary by State?

Yes. USERRA establishes a federal baseline, but states may provide additional or more generous military leave protections. State laws can differ on paid military leave, National Guard activations, drills and annual training, PTO use, benefits, seniority, reemployment and post-return termination protections.

Some states also protect activities such as Civil Air Patrol or other emergency-service duties, and coverage and employer-size requirements can vary as well.

What Notice Must an Employee Provide Before USERRA Leave?

Employees generally must provide advance notice of military service, but USERRA doesn't require a particular form. Notice can be written or verbal and may come from the employee or an appropriate military official.

Employees should provide notice as far in advance as reasonably possible, but advance notice isn't required when military necessity prevents it or when providing notice is otherwise impossible or unreasonable. The Department of Defense recommends 30 days' advance notice when feasible, but USERRA doesn't impose a universal 30-day notice requirement.

Can an Employer Require Written Military Orders?

A military leave policy for employers shouldn't require written orders in every case, since USERRA permits verbal notice and an employee may not be able to provide advance documentation.

What Notice Must Employers Provide?

Employers must notify employees of their rights, benefits, and obligations under USERRA. Posting the official "Your Rights Under USERRA" notice where other employee notices are customarily displayed can satisfy the federal notice requirement.

Does USERRA Military Leave Have to Be Paid?

USERRA doesn't generally require private employers to continue an employee's regular wages during military service. However, military leave may be paid under state law, an employer's policy, a collective bargaining agreement, an employment contract or a differential-pay arrangement.

This law also requires employees on military leave to receive the most favorable non-seniority rights and benefits provided to employees on comparable nonmilitary leaves.

Can Employers Require Employees to Use PTO?

Generally, employees may choose to use accrued vacation, annual leave, or similar paid leave while performing military service, and you, as an employer, generally can't require them to use those balances solely because they're taking military leave.

An exception may apply during a company shutdown or another period when all employees are required to use vacation, and sick leave treatment depends on applicable law, policy, and how comparable absences are handled.

What Happens to Employee Benefits During USERRA Leave?

USERRA addresses several categories of employee benefits separately from wages and PTO.

Health Insurance

For military service lasting fewer than 31 days, employees generally can't be required to pay more than their ordinary employee share of health plan premiums. For longer service, employees may elect continuation coverage for up to 24 months and may be required to pay up to 102% of the full premium.

Retirement and Pension Benefits

The USERRA Act generally treats qualifying military service as continuous employment for pension participation, vesting, and benefit accrual purposes. Returning employees may be entitled to make up missed employee contributions, while you may have corresponding contribution obligations.

Seniority-Based Rights

Seniority generally continues as though the employee had remained continuously employed, and this can affect seniority-based raises, vacation accrual rates, and other benefits.

Other Non-Seniority Benefits

Employees on military leave generally must receive the non-seniority rights and benefits provided to employees on comparable leaves. Depending on your policies and benefit plans, these may include life insurance, disability coverage, holiday treatment, bonuses, and other leave-related benefits.

How Long Can an Employee Take USERRA Leave?

USERRA law generally uses a five-year cumulative service limit with a particular employer, but it's not a simple five-year maximum.

Certain types of service are excluded from the calculation, including required Reserve and National Guard training, certain involuntary activations, service during wars or national emergencies, some service needed to complete an initial period of obligated service, and other statutory exceptions.

What Must an Employee Do to Qualify for Reemployment?

Generally, to qualify for reemployment, an employee must have:

  • Left civilian employment for qualifying service.
  • Provided advance notice unless an exception applied.
  • Stayed within the applicable five-year service limit, excluding statutory exceptions.
  • Reported back or applied for reemployment within the required period.
  • Received a qualifying separation from military service.

When Must the Employee Report Back or Apply?

The deadline depends on how long the employee was away for military service. For service of fewer than 31 days, the employee generally must report back to work by the beginning of the first full regularly scheduled work period after returning home and having at least eight hours to rest.

For service lasting 31 to 180 days, the employee generally must apply for reemployment within 14 days after completing service. For service lasting more than 180 days, the deadline is generally 90 days.

Different timelines may apply when an employee is hospitalized or recovering from an injury or illness incurred or aggravated during military service. A late application also doesn't automatically eliminate all USERRA rights. Instead, the employee may become subject to the employer's ordinary rules concerning unexcused absences.

What Documentation May the Employer Request?

For service lasting more than 30 days, you may request documentation demonstrating that the employee's application was timely, that the applicable service limit was not exceeded, and that the employee's separation from service was not disqualifying.

Which Job Must a Returning Employee Receive?

A returning employee doesn't necessarily return to the exact position they held before military service.

The USERRA Escalator Principle

The "escalator" principle generally requires the employee to receive the position they would have attained with reasonable certainty if employment had continued without the military absence.

Does the Length of Service Affect the Reemployment Position?

For service lasting 90 days or less, USERRA generally prioritizes the escalator position, followed by the pre-service position if the employee can't qualify for the escalator position after reasonable employer efforts.

Must the Employer Retrain the Returning Employee?

Yes, when reasonable efforts can help the employee qualify for the appropriate position, this may include refresher training, skill updates, or training on new equipment and systems.

How Is the Employee's Pay Determined?

Pay should reflect the proper reemployment position and the increases the employee would have received with reasonable certainty. Depending on the circumstances, this can include general wage increases, step increases, differentials, merit increases, and seniority-based increases.

What If the Returning Service Member Has a Disability?

USERRA requires reasonable efforts to help employees with service-incurred or service-aggravated disabilities qualify for the appropriate reemployment position.

If the employee can't qualify after reasonable efforts, you must consider alternative positions under USERRA's required hierarchy, generally seeking an equivalent position or the nearest reasonable approximation in seniority, status, and pay.

How Does the ADA Apply?

The ADA may provide additional protection when a returning service member has a qualifying disability and can perform essential job functions with or without reasonable accommodation.

What Other Employment Protections Does USERRA Provide?

Discrimination and Retaliation

You may not deny hiring, reemployment, retention, promotion, compensation, benefits or other employment opportunities because of an individual's past, present, or future military service or obligations. Retaliation for exercising USERRA rights or participating in an investigation is also prohibited.

Protection From Discharge After Reemployment

Employees returning from more than 30 but fewer than 181 days of service generally receive 180 days of protection from discharge except for cause. For service exceeding 180 days, that protection generally lasts one year, with you bearing the burden of establishing cause during these protected periods.

How Do USERRA and FMLA Work Together?

USERRA and the FMLA address different employment issues, but they can overlap.

FMLA Eligibility After Military Service

When an employee is reemployed under USERRA, the employee generally receives credit for the months and hours they would have worked during military service when determining FMLA eligibility. Military service can therefore count toward the FMLA's 12-month employment and 1,250-hour requirements.

FMLA Military Family Leave Is Different From USERRA Leave

USERRA law generally protects an employee who leaves work to perform military service. FMLA military family leave, by contrast, may allow an eligible employee to take qualifying leave related to a covered military deployment or up to 26 workweeks of military caregiver leave for a covered service member with a serious injury or illness.

Common USERRA Employer Mistakes

There are some common mistakes you'll want to avoid when it comes to USERRA.

Requiring Written Orders Before Granting Leave

USERRA notice may be verbal, and advance notice can be excused in certain circumstances.

Treating the Five-Year Rule as an Absolute Limit

Many common types of military service don't count toward the five-year cumulative limit.

Automatically Treating Military Leave as Unpaid

USERRA doesn't establish universal wage continuation, but state law, comparable-leave requirements, or your policies may require pay.

Forcing Employees to Use PTO

Employees generally decide whether to use available vacation or similar paid leave during military service.

Ignoring State Military Leave Laws

State law may protect additional service or provide more generous pay, benefits, or reemployment rights.

Returning the Employee to the Job They Left Without an Escalator Review

The appropriate position depends on what would have happened if the employee had remained continuously employed.

Delaying Reemployment While Waiting for Documents

Unavailable military paperwork generally doesn't allow you to postpone an otherwise valid reemployment.

Failing to Restore Benefits and Service Credit

Health coverage, pension rights, seniority, and other benefits each require appropriate review.

Assuming USERRA Is the Only Applicable Law

State military leave laws, the ADA, FMLA, and your policies may create additional obligations.
