This article is clickbait titled spam. There's a snippet of an interesting story there but not enough for a real story. The "analysis" at the end of the article is not really analysis at all. There's interesting details behind this; were they really firing him? Did Citibank make the horrible error of telling an IT worker that they are fired but not immediately revoking their privileges? Could management have handled his performance issues better, or were there red flags that he should have been let go sooner? All of that could be interesting but because this is just clickbait blog spam none of it is in the article.
