Who is more promising, the call center monitor or the trainer?

The key is yourself. Team leaders can also compete as trainers, and trainers will be eliminated if they don't cherish it. Simply from the nature of work, the promotion path of the team leader may be better, and you can go to the position of supervisor, manager or even director, depending on whether there is such a promotion channel in the call center. Trainers are specialized posts and do not belong to the management line, but good trainers are also very popular in society and belong to free and high-income people.
