The term "flying picket" is often associated with labor strikes and picketing. It refers to a group of union members who travel between different work sites, picketing them in rotation to maximize the effectiveness of the strike. However, there are a few synonyms that can also be used to describe this type of action in labor negotiations. These include "roving picket," "wandering picket," and "mobile picket." All three of these terms emphasize the mobile nature of the picketing strategy, illustrating that the union members are not tied to one specific location, but rather are able to move around to multiple job sites as needed.
