The correct answer to every single scenario is "suspend pending investigation."
Employees? Sure. Founders? I've not heard of that before.
One of the major ideas behind suspending employees for investigations is to eliminate their ability to influence the investigation. Also, it's a immediate precautionary measure to prevent the behavior from continuing should the complaint be found to be valid. In that sense, it protects the employer by keeping them at a distance in the short-term. They can also point to it in the press and in future legal proceedings (if any) as part of a strategy of showing that they took the complaint seriously from the beginning.
Gary Friedman is an excellent example (I'm lazy, so HuffPo: http://www.huffingtonpost.com/2012/08/17/gary-friedman-resto...) of a pro forma separation of a major shareholder/chairman/CEO from the company.

It's pretty standard practice to place employees on paid leave while serious complaints are investigated. You don't want to fire them until you have a pretty solid case as they might sue, but likewise you don't want them in the office.
