Legislation Limiting Strikes Weakens Union Power

Steps:

• Identify bargaining strength as a union's ability to negotiate higher wages through pressure tactics like strikes.
• Evaluate each factor's impact on union leverage against employers.
• Eliminate options that enhance union power via economic conditions, membership, or labor scarcity.
• Select the factor that restricts union actions, reducing bargaining effectiveness.

Why C is correct:

• Legislation limiting strike action directly curbs unions' primary tool for coercing employers, per labor economics principles, weakening their wage negotiation leverage.

Why the others are wrong:

• A: A rapidly growing economy boosts employer profits and demand for labor, increasing unions' ability to demand higher wages.
• B: High union membership strengthens collective action and solidarity, amplifying bargaining power through unified worker support.
• D: Short supply of workers gives unions more leverage, as employers compete for scarce labor and concede to wage demands.

Final answer: C
