Ask HN: How to deal with a senior colleague who acts like he's boss?
I&#x27;m guessing that you two are having a communication problem as it is highly unlikely that a &quot;senior colleague&quot; can&#x27;t understand simple logic.<p>To be clear, I&#x27;m not saying that the problem is entirely yours, but in most communication problems, the blame lies with both parties.  I&#x27;d suggest involving a third party (another colleague) in your conversations and allow them to moderate the discussion.<p>In my experience a third party can quickly see where the communication is breaking down, even when it&#x27;s not apparent to the two people attempting to communicate.
