Companies hired Pinkertons to

A)move employees to company towns.
B)negotiate with unions in the workplace.
C)force scabs to cross picket lines.
D)report on and bust unions.

Answer 1

To report on and bust unions.

Answer 2

I believe the answer is: D)report on and bust unions.

The pinkertons were independent detective agencies that could be hired with a high price to conduct a private investigation to anybody. At that time, many companies used their service to investigate which of their workers secretly belong in the union and fire them.
