DoD “Voluntary” Border Details: What Civilian Employees Should Document

Defense civilian employees may recently have received a memo from Defense Secretary Pete Hegseth encouraging volunteers for temporary details to the Department of Homeland Security. These assignments could last up to 180 days and would support immigration enforcement at the southwest border.

On its face, the request is framed as voluntary. But the memo also reportedly states that supervisors are expected to encourage employees to volunteer. That language matters. When a policy labeled “voluntary” is paired with leadership expectations about encouraging participation, employees understandably begin to wonder whether declining could carry consequences.

Understanding the legal difference between a true voluntary detail and a pressured one can protect both employees and supervisors.

Why the Approval Structure Raises Questions

Reporting on the memo highlights an unusual approval dynamic. If a supervisor wants to approve a volunteer request, the process appears straightforward. But if a supervisor wants to deny the request because the employee is needed in their current role, that denial reportedly must be elevated for sign-off by a flag officer or Senior Executive Service official.

That asymmetry matters in workplace dynamics. When approvals are easy but denials require higher-level review, organizational pressure can build—even if the formal policy still uses the word “voluntary.”

Federal employment law generally recognizes that voluntariness depends on real-world circumstances, not just labels. If employees face implicit pressure, career incentives, or fear of retaliation for declining an opportunity, the legal analysis can shift.

Context Inside the Defense Civilian Workforce

This memo arrives during a period of significant change inside the Department of Defense civilian workforce. Reports indicate that more than 60,000 civilian positions have recently been cut, representing roughly eight percent of the workforce. Some components, including the Army, are still exploring additional reductions while operating under hiring restrictions.

In that environment, requests for lengthy interagency details can feel different than they might during periods of staffing stability. Employees may worry about how declining opportunities could affect performance ratings, career advancement, or job security.

That anxiety is understandable—and it is precisely why careful documentation matters.

What Employees Should Document Right Now

When situations involve potentially pressured “voluntary” programs, one of the most effective protective steps is simple: create a record.

Employees should save written communications about the program, especially messages from supervisors discussing expectations or participation. If a supervisor adds commentary suggesting that volunteering would be beneficial—or declining might reflect poorly—that information should be preserved.

If comments occur verbally, write them down immediately. Note the date, time, who was present, and exactly what was said. These contemporaneous notes often become valuable evidence if questions later arise about coercion or retaliation.

Documentation does not mean conflict. It simply preserves facts.

Guidance for Supervisors Delivering the Message

Supervisors face their own challenge here. Many have been instructed to encourage participation while also maintaining a workplace free from coercion.

The safest approach is clarity. Inform employees about the opportunity, explain that participation is voluntary, and avoid statements suggesting that volunteering will affect evaluations, assignments, or advancement.

Small differences in wording can determine whether a program remains a voluntary opportunity—or becomes something legally problematic.
