Employees are experts at doing their jobs the way that they do their jobs. If they're doing their jobs inefficiently, they're experts at doing their jobs inefficiently. If employees attended a course, then they learned what the organization needed Courses are not quick fixes. After years of classroom education, most of us automatically think of learning as going to a course. We go down the list of courses in the training catalog, pick the title that seems closest to what we're doing and we sign up for the course.
Many supervisors work the same way.
After an employee comes back from a course, all one can really say for sure is that they came back from a course. However, there are several basic things a supervisor and employee can do to ensure the right form of training is selected and that the training provides results in the workplace. Besides, taking a course is only one of the many ways in which employees can learn. There's no use sending employees to a course. The perception that training is a waste of time is tragic.
