> I don't think that's necessarily true. Another interpretation of being hired as a salaried employee might be "they get the work done that they were assigned, in a satisfactory manner, and are able to respond during regular work hours when needed". If someone can hold two jobs and fulfill that, then why is that a problem?

If that's true, then there shouldn't be any concern about sharing with them that you're working another job at the same time.

Like I said, I don't have a problem with it if each employer is aware and is fine with the situation. IMO the ethical question is if you are lying to one or both parties.
