ex1: Labor Unions push for minimum wage increases Minimum wage increases the labor cost for businesses using low-cost employees. This also decreases the gap between the wage rate of low-skilled and high-skilled workers; high-skilled workers are more likely to represented by their union ex2: Support restrictions on imported goods through quota and tariffs. this increases the demand for domestic production and, therefore domestic labor. ex3: Lobbying for stricter immigration rules. This limits growth within the businesses causing the low-skilled workers to not apply. Similar to the effect of increasing minimum wage. this makes non-immigrants and high-skilled workers more attractive to businesses. *hope this helps - good luck*
