(Literally, "warning strike".) Form of industrial action which is usually of brief duration and not directly aimed at achieving demands but intended to warn the employer that confrontational forms of action will be used. Although its main purpose is to demonstrate the strikers' determination, in order to be lawful it must be called in connection with particular claims (see strike ).
