Question to Ask the Workplace Doctors about warnings:
I would like to know if a manager-in-training is allowed to give a verbal warning?
There may be varying rules in different organizations, but in reality one cannot learn to fulfill the role of a manager without doing it, so managers in training must do the work of a manager-which would include work-related warnings if needed. (It is like being a teacher, doctor or salesperson in training. The only way to learn is to do.)
