Mc) which factor limited the growth of union membership among unskilled workers during the late 19th and early 20th centuries? legal restrictions on strikes and collective bargaining the outsourcing of unskilled jobs to foreign labor markets the growth of the unskilled workforce as a result of immigration a rise in wages among unskilled workers who were not in unions

The answer to the question above is the third option: the growth of the unskilled workforce as a result of immigration.
