Yeah, I faced a situation where I politely declined the offer of one of my colleagues and his behavior changed and it really affected work. I had just joined the company and he was supposed to put me up on my trainings and all. At first I tried to stay professional, you know, handle it in a professional way. I reached out to him when I had issues with some of the tasks. I was not understanding then, but his behavior did not change. I still continued, I was still professional and all. When I saw how much of an impact it was affecting on my work and I knew I had to escalate it further to a supervisor. And then after doing that, it stopped. His behavior stopped and everything went back to normal. It really taught me the essence of knowing when and when to escalate to management on some issues. But today we are good, we are cool, we are working together, but it really helped me know when and when to escalate things to management. And it really made working now a bit easier because management had to intervene and it worked well.
