Not US but in Canada my old employer attempted to have me sign a new contract for a change of role stating I would get explicit allowance if doing any other work including volunteer work. And to note the other commenter volunteer work was specifically noted. Needless to say I took that as a good sign to move on :) My current employer has a much more reasonable policy that I can't work a second job when on my scheduled hours with them.
