Do employers have to pay employees for mandatory training

https://law.moj.gov.tw/ENG/LawClass/LawAll.aspx?pcode=N0030001

I’ve read through the Labour Standards Act and I can’t see anything related to this. Possibly Article 15-1 comes closest.

If an employee is part time or a contractor, is the employer required to pay the employee for mandatory training? Or, is unpaid mandatory training considered acceptable in Taiwan?

Thank you very much in advance.
