I telecommute full time for my job as a copy editor for a large business Web site. I plan to spend a month in the Caribbean. Is it ethical to do this without running it by my supervisor? My online presence will remain the same; only my physical location will change. -- Name Withheld

If your duties are truly unmoored to place -- you never drop by the office to swipe supplies (I mean, consult with colleagues face to face) -- then pack your laptop and sunscreen and head south. Your supervisor has an interest in how, not where, you do the job. Unless you anticipate a decline in the quality of your work -- Antillean computer problems, cell phone vagaries, cataracts and hurricanos that spout until they drench your steeples and drown the cocks, sulfurous and thought-executing fires, oak-cleaving thunderbolts or simply the Siren song of the wi-fi-less beach -- I don't see why this is any of your supervisor's business. But you might want to mention it: to give information, not to get permission.
