Civilian Career Paths

Career associations are editorial assessments of the cited evidence, not an official crosswalk unless the evidence explicitly says so. O*NET supplies civilian occupation information, not proof of a military match. Related experience does not confer civilian qualifications. Tasks and tools below describe civilian work, not military training.

Human Resources Managers

Oversight of personnel utilization, performance, care, and conduct provides a basis for coordinating workforce needs and employee relations.

How to prepare: Complete a civilian employee-relations course covering disciplinary procedures and labor-contract interpretation. Also check employers' expectations for relevant civilian HR experience and a bachelor's degree or employer-accepted equivalent, since the verified duties do not establish experience in compensation, employment law, or labor relations.

What the civilian work involves

Plan, direct, supervise, and coordinate work activities of subordinates and staff relating to employment, compensation, labor relations, and employee relations.
Perform difficult staffing duties, including dealing with understaffing, refereeing disputes, firing employees, and administering disciplinary procedures.

Civilian tools and software (examples)
