Law of effect suggests that it is more likely for the responses to occur again in the future that creates enjoyable, positive, and satisfying experiences/feelings as a result of a certain situation. On the contrary, the responses that produce negative feelings, discomfort, and uneasiness are less likely to occur again in the future.
This is a very common phenomenon that we face in our everyday life. We want things to repeat that brings comfort, joy, and other positive reactions and we want to avoid creating or participate in such situations where negative feelings and emotions such as discomfort would result.
In Management, the Law of Effect can be explained as an example of an employee who is always happy and productive on a routine task, however, when he moves to another (new) task, he feels uncomfortable and is much less productive.
