What are the following types of training should employers NOT provide to their workers?

Employers should avoid providing training that is irrelevant to employees' roles or the company's goals, as it wastes time and resources. Additionally, any training that promotes discriminatory practices or harassment should be strictly prohibited, as it violates workplace ethics and legal standards. Training that is overly theoretical without practical application may also lead to disengagement and decreased productivity. Lastly, employers should steer clear of any training that lacks proper accreditation or fails to meet industry standards.
