Accepted Answer

16 down reads "Working at home, waiting" (2,7 letters); the answer is IN SERVICE. It's a charade: the answer breaks into parts in clue order, each part clued by a word or short phrase. No indicators needed; watch for standard abbreviations (RA = artist, US = American, IN = at home) and short synonyms. The full step-by-step breakdown is on this page.
