Three ways that unions made their opinions known were through:

strikes
collective bargaining
support of labor legislation
blacklisting

Three of those are right. What do you think they are?

COLLECTIVE BARGAINING

STRIKES
Blacklisting

To identify the ways that unions made their opinions known, we need to review each option and determine if it applies.

1. Strikes: Unions have historically used strikes as a means to protest and make their demands known. During a strike, workers collectively refuse to work until their grievances are addressed. Strikes can be an effective way for unions to demonstrate their strength and negotiate better working conditions or wages.

2. Collective bargaining: This refers to the process of negotiation between employers and labor unions to determine terms and conditions of employment. Unions often engage in collective bargaining to advocate for their members' interests, such as higher wages, improved benefits, or better working conditions.

3. Support of labor legislation: Unions actively lobby and advocate for labor legislation that protects workers' rights and advances their interests. This can involve supporting or opposing specific laws, pushing for reforms, and working with lawmakers to shape labor-related policies.

4. Blacklisting: This term refers to the practice of employers actively excluding and discriminating against individuals who were perceived as union sympathizers or organizers. While blacklisting was a strategy used against unions by employers, it is not a method through which unions made their opinions known.

Therefore, the correct options among the given choices are:

- Strikes
- Collective bargaining
- Support of labor legislation
