Final answer:
The question seems to hint towards the historical role of porters in railway services and labor dynamics, resembling situations like the 2015 dispute between longshoremen and shipping companies.
Step-by-step explanation:
The original question related to porters and their role in relieving railroad clerks does not provide a complete context to offer a definitive answer. However, from a historical perspective, porters were often employed in various capacities to support the functioning of railroads, including assisting clerks with baggage, customer service, and other tasks, particularly during the time when rail travel was a primary mode of transportation. Labor-related disputes in various industries are not uncommon, such as the 2015 incident concerning longshoremen and shipping companies that resulted in the use of the Taft-Hartley Act.
