I am at a point where I am not enjoying my current role anymore. I am thinking to start networking within my current company to explore some of the roles that I might be interested in. Am I suppose to inform my manager explicitly about it? If I do so, I am a little concerned that it would alarm my manager even when I don't have anything concrete right now and would do more damage to me.
Note: I am not saying that I intend to apply for a job within my company without telling my current manager. All I am asking is about networking and informational interview type activities and just to discuss my career interests.
