What term describes a group of workers from the same or different crafts who operate as a unit under common authority?

The term that accurately reflects a group of workers from the same or different crafts who operate as a unit under common authority is "Cooperative Crew." This term emphasizes the collaborative nature of the workforce, where members come together, regardless of their individual specialties or trades, to work towards a common goal while being guided by a unified leadership structure.

Using the term "Cooperative Crew" signifies an organized approach to work, highlighting teamwork and coordination among various crafts. This is critical in rail mechanics, where different skill sets are often needed for complex tasks and projects, requiring effective collaboration and communication within the crew to ensure safety and efficiency in operations. The focus on unity under a common authority also reinforces the importance of leadership and direction in achieving successful outcomes in a rail environment.

The other options do not convey the same sense of organized collaboration and leadership unity. "Team of Experts" implies a focus on individual specialization rather than collective operation, while "Group of Workers" is too vague and lacks emphasis on the organized nature of the working unit. "Union Workforce" specifically refers to workers organized within a labor union context, which may not adequately address the mix of different crafts working together under common authority.
