Having more workers than the job actually needs. It is an adjective, used of a company, a factory, an industry, a department, a ship: the shipyards were badly overmanned, an overmanned and unprofitable railway. The word belongs to business and economics writing, and it usually arrives just before bad news — it is what managers and journalists say when they are about to argue for cutting jobs. So the word is not neutral; it takes the company's side of the argument. Two more things. It is chiefly British, and it is dated: it was everywhere in British newspapers of the 1970s and 80s, during the arguments about state-owned industry and union power, and it sounds of that time now. And because "man" sits inside it, many organisations avoid it today and write "overstaffed" instead, which means the same and offends no one. If you are learning one of the two, learn "overstaffed".
