At my job we are working on a project that will span abot 4 years. The project manager (who is the Director of Ops) refuses to have regular meetings and provide information. I think of it as a death march- setting us up for failure. We all scramble for bits of info to complete our part, and without the whole integrated picture this can cause delays, frustration and misinformation. Any attempts to help the PM are brusquely ignored or waved away. I think that he does this to make the rest of us look like idiots, and he is the savior. In any case, going to HR does no good. I would like to deal with this in an open and honest fashion, trying to make him look bad will only backfire and not improve the situation.
Would appreciate you feedback on working with info-hoarders and people with power who are insecure in their role.

I was a project manager for over 20-years and you are in a no win situation.
You are most likely correct in your assumption of why the PM is not sharing information.
When you are dealing with this type of personality, anything you do will be met with resistance because the PM doe’s not want to share power and glory for a job well done.
If your HR department refuses to deal with this, you really cant do a whole lot but set back do the best you can and cover your butt.
I’m in this situation right now, and my last day with the company is Friday. After 2 years of dealing with work hoarding and insecurity I just decided it was in my best interest to go someplace else.
I agree with you that going to HR is pointless in this situation and retaliating against your manager isn’t going to do anything, especially if he’s worried about his team members showing him up. Basically, the only option that you have is to bring it up with the manager directly, and if you can get some co-workers to join it might help.
Sadly, though, in my experience, these types of people can’t be reasoned with. If you really feel like you are on a “death march” you will probably want to start looking for a new position. Don’t let a lousy manager ruin your reputation by setting you up for failure.
Best of luck.
