Premier Tom Marshall's office says his chief of staff held meetings and spoke with Nathan Whalen, the president of the organization, after the complaint.
Whalen had said he felt intimidated during a confrontation with Education Minister Clyde Jackman during a conversation on the day the spring budget was delivered.
He wrote a letter after the April 3 encounter, alleging he was bullied by Jackman, but the minister described the conversation as a disagreement and said he did nothing wrong.
The premier's office says in an email that Jackman and Whalen met, shook hands and committed to putting the disagreement behind them.
Whalen says he is willing to move on.
