People with the ISTJ personality type enjoy taking responsibility for their actions, and take pride in the work. They do not stint on their time and energy and finish each task with accuracy and patience. ISTJs don't make assumptions, preferring instead to analyze their surroundings, check their facts and arrive at practical courses of action. ISTJs have little tolerance for indecisiveness, but lose patience even more quickly if their chosen course is challenged with impractical theories, especially if they ignore key details—if challenges become time-consuming debates. ISTJs can become noticeably angry as deadlines draw nearer.

This sense of personal integrity is core to ISTJs and goes beyond their own minds. ISTJ personalities adhere to established rules and guidelines regardless of cost, reporting their own mistakes, and telling the truth even when the consequences of doing so could be disastrous. To ISTJs, honesty is far more important than emotional considerations, and their blunt approach leaves others with the false impression that ISTJs are cold, or even robotic. People with this type may struggle to express emotion or affection outwardly, but the suggestion that they don't feel, or worse, have no personality at all, is deeply hurtful. ISTJs need to remember to take care of themselves because their stubborn dedication to stability and efficiency can create an emotional stress that can go unexpressed for years, manifesting when it is too late to be treated:

When it comes to the workplace, ISTJs are almost a stereotype for the classic, hardworking, and dutiful employee. In all positions, the ISTJ personality type seeks structure, clearly defined rules, and respect for authority and hierarchy. Responsibilities are not burdens to ISTJs, they are the trust that has been placed in them—an opportunity to prove once again that they are the right person for the job. On the other hand, the change that comes with assuming new responsibilities, or in losing old ones, is often a significant struggle for ISTJs. Depending on the position of authority the ISTJ is in—assuming new responsibilities presents as one of the most significant challenges to overcome. However, it is one of ISTJs' most significant challenges to overcome.

Let's learn the main traits of the ENTJ at work as an employee, subordinate and manager with the help of the following chart:

Emotional intelligence-wise, ISTJ's are composed and often internalize their emotions, which every so often can be harmful because when they bottle up their emotions they will overreact when others rub them up the wrong way. Thus, ISTJs need to take actions to improve their emotional intelligence in the following areas:

• Emotional self-awareness and self-management: Usually, ISTJs resort to reason to assess their emotions inwardly, and bottle them up, which is not good for their personal wellbeing or to work well in group situations. They should learn how to be more mindful in all areas, how to relax, and how to use more abstract ideas. They should also learn to investigate their emotional triggers at a root level so that they can improve their emotional self-awareness and self-management.
• Social awareness and social skills: ISTJ depend so much on their introverted nature, they find it difficult to grasp how others are feeling, so they don't react accordingly, therefore, they can come across as a bit harsh because of their lack of consideration for others, showing their lack of empathy. To improve their social skills, ISTJs need to learn and practice to be more empathetic in the presence of others, by agreeably expressing their feelings, adjusting their reasoning-oriented mind. ISTJs type should open themselves up to the emotions of others while coming to terms with their own emotions, thus helping them to be more receptive to enhancing their emotional intelligence.
