The political party associated with this slogan is Option B: Democratic.

Explanation:

This bumper sticker slogan is associated with the democratic party in the United States.  This is because the democratic party is traditionally associated with union organizing and more concern for the working class who tend to worry about job creation and the unemployment rate in deciding on which political candidates to support. Industrial unions worked to reelect President Franklin Roosevelt in 1936, organized labor and the Democratic Party have worked together in U.S. politics.  A Gallup poll conducted in 2019 found that 82 percent of Democrats approve of unions, according to the New York Times, although less than 11 percent of the population belongs to a union according to 2018 figures from the United States Bureau of Labor.
