The two correct answers regarding the negative impact of the Pullman Strike on early labor unions are:
- The strike became violent as did the Homestead Strike and the Haymarket Affair.
- It helped create a negative public opinion of labor unions.
The Pullman Strike, along with other violent labor disputes of the time, contributed to a perception of labor unions as chaotic and prone to violence, which hindered their efforts for reform and collective bargaining in the future.
