Salaried employees are much more likely to train outside of the office since they can pick locations/times which are much more convenient for themselves.
Question: How common is it to have employees take the online training at home?
My Response: Salaried employees tend to be more motivated to train on their own time. If the training is required for the job function, hourly employees are very unlikely to train on their own time. It is best to make time during their shift or provide access before or after their shift.
After the required training is completed, some companies have had success getting hourly employees to conduct advancement training on their own time... but these company typically have other incentives such as bonuses or pay increases after the training is complete. Such incentives make this additional effort worthwhile.
