Can Learners withdraw from 'Required' learning, or does the Learning specialist have to withdraw them? 

I found the following note on Support, but it does not specify if a Learner enrols himself in required training, if he can withdraw:

"Learners do not have the possibility to withdraw from the course as it is assigned as Required Learning From the Line Manager. If Line Manager thinks that any Course is not Required, he can assign it as Recommended Learning and there Learner has possibility to withdraw. Learning Specialist has the ability to withdraw learners from a Required Course types."
