Hey everyone, I started 6 months ago at a large firm as an audit associate, not a big 4 firm. Recently a senior associate was fired, and nobody else knows why other than it may have been performance related. I never worked with him so I can’t speak on the quality of his work but to me it seemed pretty shocking because I at least thought he was one of our better seniors. Everyone loved the guy and he showed up every day (not that that matters entirely since we’re hybrid remote). This happened right in the middle of busy season and it’s been hectic for that engagement team having to bring in a new senior to take over. I’m new and wanna do the best I can to avoid being in a similar situation, so my question to you all is simply what do you think would have gotten him fired that way? Is this normal? As an associate, how do I avoid the risk of something like this happening to myself?
