its not fair too for the old manager sigcamp "A" when he/she watch the member of that manager "A" is trying to apply into another sigcamp "B" but in the sametime that person is still active in that old sigcamp "A".
if you want to search for better payment, then you should learn to let it what you've got in the past, and trying for another chance to get better payment in future.
i am sorry if i make mistake, i am not have any purpose in this situation, i just want to make it clear for others so we can thinking how does the old manager feels when he/she knows that his/her member its active in the old sigcamp but that member its make an apply for new sigcamp.
ussualy if you join signature campaign A and you leave
and you join signature campaign B and you if kick out campaign B
you can't back again in signature campaign A, very dificult you can back again only few time in accident
