> If you can't talk to your manager about that kind of thing and expect some help (or at least some advice/sympathy),
Perhaps I'm imagining it, but I believe this always has a side effect of incrementing a little counter in manager's head - one labeled "oh, they're failing to deliver again". The first few times around you might get sympathy, but then you'll start seeing irritation, and few rounds later you'll find yourself on a Performance Improvement Plan.
If you're constantly failing to deliver at the same rate and level as your co-workers, yes it is going to increment a counter.
If you're delivering work though, and keeping management aware of blockers that need to be resolved, then no it wouldn't. I've seen more co-workers wind up on management's bad side because they were afraid to say when something was going sideways than ones that asked for resources or help resolving a problem. Turns out management hates it when they think something is on track and then 2 days before the estimated due date they find out "we're 6 months behind" a lot more than they hate hearing "we need some resources to resolve X Y and Z or we will need an extra 6 months"
They generally can tell who is failing to deliver because they are constantly stuck on trivial things and who genuinely can’t do more and need help. If you go see your manager because the team next door is blocking you explaining clearly what you have tried and why you need the issue to be escalated you just sound professional. Same thing if you can tell you are going to be late in your delivery and need something specific done to help especially if you do it with a lot of time left.
Also I have a pro-tip. Managers intentionally ask people they view as competent and trustworthy to do the thorny things that need to get done. So surprisingly the people who are expected to need the most help are often the most valued.
