Because every company and enterprise have different calculations on training, just like the company where Xiaoke once stayed, training is not overtime, but the company asks someone to give you training knowledge, so that you will not fall behind and keep up with other people's ideas in the future, so it is not overtime at that time.
However, there are also some companies, such as public institutions. Attending training on weekends usually counts as overtime, but many people won't let you go on weekends and will let you go from Monday to Friday.
It depends on your own company. If you train every weekend, you can ask. After all, everyone will feel uncomfortable wasting one day a week and taking up your time without telling you whether to work overtime or for free.
But only once or twice, so don't ask. If you ask the leader, your leader will only remember that you are a person and you are not worthy of promotion.
Don't ask if you can. Anyway, we will know when we get paid.
