In such a situation, please contact HR or the superior of the related superior in the workplace immediately and solve the problem. There is the suspicion of the power harassment of the superior who says the comment like this. We should keep the workplace environment where each of us can demonstrate the maximum ability. If the subordinates are scared of the superior's comments and behaviors and then, the subordinates cannot consult with the superior, there easily occur the mistake on the business. Even though the mistake was made by the subordinate, the superior should not relentlessly blame the subordinate for a long time. Instead of that, the superior needs to indicate the future improvement measures and countermeasures. The side of the superior should consciously make the workplace environment where both of the superior and the subordinates can exchange the free and open opinions in the workplace!
