Frustration is a very common negative emotional experience at work in a customer environment that can arise in a variety of circumstances, usually present when our goals are blocked, we have some degree of uncertainty about the causes of the problem, we think this situation is unfair, and we can’t control things. What happens once we feel frustrated is that we can either « let it go » or persevere, and what we do in terms of taking action can depend on both personal and environmental factors.
