See Priscilla, I will be very blunt with you on this (with my limited but rather grilling experience at corporate so far) – This guy is a dick but don’t his behavior too personally. A lot of workplaces have this culture at times where the people who are meant to manage and supervise us only do the bare minimum to get by – they arent displaying that dynamism to answer more questions. They usually survive if HR is lazier still and they know how to butter up their superiors well.

My suggestion is discuss the area of brainstorm with someone of a higher designation if possible – do not mention this person’s attitude in any way though. It is fine to be irritated with this attitude – it happens to all of us but do not take it personally in any way – it is a poor reflection of him, not you and eventually you will rise above if you keep doing your work well, displaying initiative and interest to your superiors. However, as a professional, and even in life in general, it is better you dont allow this one irritating person to have this kind of power over you. I understand you cant control his reactions but you can control yours.

If you feel that your organization is not offering you the environment that is conducive to the kind of brain-storming you enjoy, look for newer opportunities in others.
