My general tips (not always possible or applicable, but hey): - Highlight the cost of doing what he says. There is always a cost, but either you or him/her may be misunderstanding or miscalculating it. - Ask why it needs to be done. - Offer alternatives. - Keep in mind he/she has more to lose than you if the conversation goes bad. - Stay polite.
