Final answer:
After Elsa filed a complaint with her union, the Heat & Frost Workers of America, the union representatives may try to negotiate with management. If negotiations fail, the union might authorize a strike or take further legal action, potentially involving the NLRB or triggering government intervention with a "cooling-off period".
Step-by-step explanation:
When Elsa wasn’t paid time and a half for overtime for her work at Frozen Castles, Inc., and she complained to the Heat & Frost Workers of America, her union, several actions could ensue. Typically, the union representatives would first try to negotiate with the management of Frozen Castles, Inc. Unions historically have played a crucial role in representing workers to plead for fair wages and working conditions, often leading to strikes if management refuses to negotiate.
In the event of failed negotiations, the union could authorize a strike, during which the union members collectively stop working to pressure the company to address their demands. This tactic has been used successfully in the past, as with the Homestead Strike or the Lawrence Textile Strike, although it can also lead to serious conflicts and even government intervention. For instance, the government can impose a "cooling-off period" to force employees back to work temporarily while negotiations continue.
If these steps are unsuccessful, further legal action could be taken, and the case could escalate to higher authorities, including involvement from government agencies that oversee labor disputes, such as the National Labor Relations Board (NLRB).
