"First, I would use my best judgment about when to intervene, and if the employee was truly disrupting the learning of others, I wouldn't hesitate to call them out or dismiss them from the training. If the actions called for it, I would report it to their supervisor following the training. Last year, I had a very outspoken gentleman in a training session who was using foul language. I simply requested that we keep all conversations PG in nature and he was very quick to stop using the language that was making others uncomfortable. The direct approach worked. Another time a few years back, there were two employees that were laughing with each other, texting, and simply being too loud for others around them in a room of about 30 people. I warned them once in front of the group to please stop. When they continued again, I asked them to leave and let their manager know immediately. I take the learning opportunities that I provide to employees seriously and also expect that same respect out my learners at all times."
