At work, the ISFJ is motivated by the desire to help others in a practical, organized way. ISFJs are driven by their core of personal values, which often include upholding tradition, taking care of others, and working hard.

ISFJs enjoy work that requires careful attention to detail and adherence to established procedures, and like to be efficient and structured in their completion of tasks. They prefer an explicit authority structure and clear expectations.

ISFJs usually prefer to work behind the scenes, and like to receive recognition in a low-key way without being required to present their work publicly. They want to feel that they have fulfilled their duties, but do not want to be thrust into the spotlight.

An ideal job for an ISFJ involves well-defined work tasks that achieve a concrete or observable result, and does not require a lot of multi-tasking. An ideal work environment for an ISFJ is orderly, provides plenty of privacy, and includes colleagues who share the ISFJ’s values.

ISFJs are supportive, organized team members who attend to the needs of the people around them and follow procedures to get things done. ISFJs are not often interested in leading a team, but may naturally take on the role of group secretary, keeping meticulous notes and accurately recalling facts and details that are important to the group process.

ISFJs are sensitive to the concerns and emotions of others and do best on cooperative teams where there is not too much conflict. ISFJs typically feel most secure on a team where everyone adheres to established rules and procedures; they generally believe that people get along best when they all follow the rules. Team members who question the rules—or worse, ignore them outright—may upset the ISFJ, who wants a harmonious, predictable environment.
