asertivity

On the lesson of Thursday, we talked about how to be assertive.
At first we watched a video on youtube. In the first half of the video there were a boss and an employee, the tune of the video was hardly understandable because of the wrong quality, so I just could get a few words, but it was obvious, that the boss was very angry and aggressive with the employee after he had made some mistakes. After that we wrote dialogues in pairs between the boss and the employee, but in these dialogues the boss had to be assertive. Firstly I had to search for this word "assertive", because I had never heard it before, but now I know. It means, that you know, what you want and you are able to convince the others not in an aggressive way, but in a polite, clear, understandable way without any breach. So 3 of the pairs performed their dialogues, but in my opinion just one of them was good enough and the others were either too passive or too aggressive. The teacher said that next time she will tell us some solutions, how we can be assertive in a perfect way, so on next Tuesday we will study it correctly.
