Money
In yesterday’s The Ethicist, Randy Cohen tackled this “stumper” of a question:

I hire freelance artists for a national magazine facing tough financial times. Must I tell them that they might be paid late or perhaps not at all? If I do, they might decline the job, and we cannot produce the magazine. If I don’t, I burn a lot of bridges. My superiors assured me that they will start paying contributors, but they said that for months with no results.

“You may not tell a lie to your freelancers, even a lie of omission, even for the good of the magazine.”

The rest of the answer, which is pretty strongly worded, is here.
