How many IUEC work stoppages?

As of my last update in October 2023, there have been multiple work stoppages involving the International Union of Elevator Constructors (IUEC) over the years, primarily concerning contract negotiations and labor disputes. However, the specific number of work stoppages can vary, and detailed statistics may not be readily available. For the most accurate and current information, it would be best to consult IUEC's official communications or labor reports.
