Which of the following describes a primary difference between craft and industrial unions?

A) Workers from labor-intensive fields (like manufacturing and agriculture) form craft unions, not industrial unions.
B) Workers of a particular trade, not an entire industry, form an industrial union
C) Workers from labor-intensive fields (like manufacturing and agriculture) form industrial unions, not craft unions.
D) Workers of a particular trade, not an entire industry, form a craft union.

D) Workers of a particular trade, not an entire industry, form a craft union.

B) Workers of a particular trade, not an entire industry, form an industrial union.

To determine the correct answer, let's break down the terms and analyze the options:

- Craft unions: These are labor organizations that represent workers of a particular trade or craft, such as electricians or plumbers. Craft unions protect the interests of workers with specialized skills in a specific industry.

- Industrial unions: These are labor organizations that represent workers across various trades or industries. Industrial unions typically gather workers from multiple trades in a particular industry, such as automotive or steel.

Now, let's consider the given options:

A) Workers from labor-intensive fields (like manufacturing and agriculture) form craft unions, not industrial unions.
This option states that workers from labor-intensive fields form craft unions, excluding industrial unions. However, it doesn't capture the essence of the difference between the two types of unions.

B) Workers of a particular trade, not an entire industry, form an industrial union.
This option correctly describes the main distinction between craft and industrial unions. It states that workers of a specific trade, not an entire industry, form industrial unions. This reflects the idea that industrial unions represent workers from multiple trades within a specific industry.

C) Workers from labor-intensive fields (like manufacturing and agriculture) form industrial unions, not craft unions.
This option incorrectly states that workers from labor-intensive fields form industrial unions, not craft unions. It doesn't accurately define the relationship between the types of unions.

D) Workers of a particular trade, not an entire industry, form a craft union.
This option incorrectly states that workers of a particular trade form craft unions. While workers of a particular trade do form craft unions, this concept alone does not encapsulate the primary difference between craft and industrial unions.

Therefore, the correct answer is B) Workers of a particular trade, not an entire industry, form an industrial union.
