How do I avoid personal problems with my manager
Hey guys, I work as a data analyst in a small team and while working on a project, I criticized my manager's way of solving the software problem, and I proposed a better and cheaper solution, but he strongly rejected it, even though my solution saved 70 percent of the time and effort, so I had to file a report and send it to the company's management and they actually agreed to my proposal and a financial reward was paid to me.
But you know, some people don't like to be outdone, yes you probably have one of them in your team, anyway after this problem my team manager become very hostile towards me and he assigned me very ridiculous tasks.
How do I explain to him that I only did what I did because I wanted to protect our company's interests???
