Answer: True
Step-by-step explanation:
The main reason that can be attributed to AFL not recognizing CIO when it was still growing was due to the fact that there was a disagreement over the inclusion of craft unions and industrial unions in the AFL which Samuel Gompers was the leader and membership were only to skilled workers.
Later, John Lewis, whom was the president of United Mine Workers, made a proposal stating that unskilled workers should be included in the industrial unions and this was rejected which led to Lewis breaking with AFL and then went to form CIO.
