Their central desire is to be useful and to be able to comply. As the most self-denying of all types, they approach work with a kind of sacred devotion and dedication, since for them work is inherently good and fun must be earned. They are remarkably reliable at work, but struggle when they must deal with situations where conditions, demands, or regulations keep changing. They seem almost genetically coded for compassion toward all kinds of suffering, and more than others they are capable of humility and service. We find them at mid-management levels in various administrative roles, and they can also make excellent professional ecologists. In employment they tend to be devoted and loyal workers, bonded more to their superiors than to their department or company. They hold their work to high standards. If someone doesn't act or behave as they should and as can rightfully be expected of them, ISFJs become uneasy or irritated, almost taking it as a personal offense. They are naturally frugal and thrifty, and dislike seeing waste of any kind, anywhere. They expect others to behave according to their assigned role. Their workplace is a model of order, with everything in its place. Pleasant, reliable, perceptive, and sensitive, they are every manager's dream. They approach work methodically, step by step and with deliberation, finishing at just the right time. They are not the most brilliant at generating new ideas, but they handle details well and don't mind routine. The true value of the quiet support and sense of security that comes with having these people in the workplace is something many only come to appreciate once the ISFJ has left.
