In some circumstances, there could be more implications with publicly traded companies.

Even then though, the only ramification the employee would suffer would be termination 95/100 times.

Civil cases cost money, and they don't recover anything from most employees, at all. (exemptions and bankruptcy protection). So a civil case is little more than a great way for a company to flush another $250k away, unless the employee is very rich and has no asset protections in place, which is uncommon.
