Usually it pertains to a manager of those who perform the actual duties. For example, the general manager may be up in an office somewhere doing all paperwork and the floor manager is actually on the floor in charge of and supervising those who are actually building the product or performing some duty. The floor manager usually reports to the general manager and if the general manager notices a problem, he would have the floor manager address it. I hope that helps.
floor manager? well, if it were used in a czech ad, it would most likely mean "cleaning woman", now that the english job/position designations come into vogue, it is not uncommon to see terms like "logistics supervisor" (read: "senior forklift driver") or "public nutrition specialist" ("burger flipper")
