I had a bad talk with my boss!

Most managers can't care less about the employee's well being they just want the employee as a cash cow making money for the company, and the moment the employee falters, they will harass him/her to termination. I learned this from my brother, who is an employment lawyer with 10+ years of experience.

Depends where in the world you are, and the organization culture of where you work. I’ve been fortunate enough to work for corporates where this isn’t the case. Managers do care about their team. Altruism? Not always, as the success of the team reflects on the ability of the manager - great team = path to career progress etc.

Business has two main reasons to hire people - revenue generation (potential profit) and risk mitigation (loss of revenue/profit). When a manager tells you where you can improve, they still believe you can do one of those things. Tough conversations are healthy. (But not fun) If they’re giving you feedback that’s a good sign. Take it and learn from it and assume your manager is trying their best. The role of a manager is super hard, and often they’re not provided much training on now to coach and lead their team.

Take it professionally, not personally.

Yrrr take some time for self-care, talk to a friend or family member about this. Can anyone please suggest some strategies for managing stress and improving your mood under such situations?

oh man.. this is something that will take some time to process your feelings. Try to talk to someone you trust. Focusing on the positives in your work or setting realistic goals for yourself could also help. Remember, it's okay to feel upset, but try to focus on moving forward. How can you apply these strategies to your situation and improve your mood?
