One day my boss sent in our team chat group a screenshot of his conversations with one of his former subordinates who is now working in a giant. In a conversation my former colleague(the mentioned guy) kind of flattered him that what she was doing in our company was much more advanced than what she is doing now in the new company. And thus my boss encouraged us that we should be confident in what we are doing now.
But many of my colleagues and I just disagreed with his blind self-confidence, and we discussed the facts and the true gap offline. One of my colleagues said in the chat group that it would be untrue and provided some strong evidence, and our boss didn't say anything more. I think he may have realized his mistake.
I think his motives are good but he didn't find the right method, but I don't know how to save his face and realize his purpose: build the team's confidence and help the team to grow? Is it possible?
