Everyone can display their anger productively; while expressing it is usually done in four ways: aggressively, passively-aggressively, suppressing it, or declaring it, while only the last of these ways is healthy. When expressing anger aggressively, people may, for example, throw things and hit something. Passive aggression occurs when a person takes offense at someone or blames others for a conflict. Suppression of anger can be expressed through denial that the person is upset.
When people declare that they are not happy but do not blame others or insist on their righteousness, this is how it becomes possible to express anger productively. I thought it would be appropriate to mention here the online article by Amy Morin on management techniques. In it, the author points out effective and simple strategies for dealing with hostility. As you rightly noted in your presentation, “each person may have a feeling of anger, but the trigger differs”. I think the critical question is how to deal with it? Jacobson wrote that people must address anger carefully and thoroughly. I think it can be helpful to perceive hostility as a reason to shift your focus from the outside world to what is going on within you and develop self-compassion.
