More precisely referred to as "action drafting," the worker placement mechanic requires players to draft individual actions from a set that is available to all players. In a given round, drafting is done one at a time and in turn order until all players have had a chance to draft individual actions. There is usually a limit on the number of times a single action may be drafted each round. In truth, there are many who feel that 'action blocking' is a defining element of worker placement, but this is not always the case, as there is not always a limit on the number of times a single action may be drafted each round.
