Really, there's very little, if any, though I will mention some.
Benefits: I joined during a time when the company that actually hired me was being bought out by L3Harris as a whole and our benefits kept constantly changing. This was more of an annoyance than a legitimate issue.
Restructuring: This is largely due to COVID-19 and I don't really think that anyone could have predicted what would've happened to our company's industries so I don't think this is inherently a problem.
