Final answer:
The correct answer is 3) Decrease in union membership. Labor unions have made progress in areas such as minimum wage, worker protections, and paid family leave, but the decrease in union membership is not a recent sign of progress.
Step-by-step explanation:
The correct answer to the question is 3) Decrease in union membership.
In recent years, labor unions have made progress in several areas to benefit American workers. These include increasing the minimum wage to ensure fair compensation, expanding worker protections such as anti-discrimination laws and safety regulations, and advocating for paid family leave to support work-life balance.
However, the decrease in union membership is not a sign of progress made by labor unions. It indicates a decline in the number of workers associating themselves with unions, which can be attributed to various factors including changes in labor laws, shifting job market dynamics, and alternative forms of worker representation.
