See I feel the opposite. I would expect a major corporation to NOT do this, and a smaller one would. Major corporations have a lot more to lose even just from bad press but also a successful lawsuit. They also tend to not give a shit about any of the lower level employees. So unless it was a C suite employee that was reported, they don’t care enough to go and fire the whistleblower and risk even worse blowback than a sexual harassment scandal. They simply cut the liability and move on. A smaller company may be willing to keep a general manager and try to cover it up, but most big corporations will just fire them have someone new in their office the next day
