@phryk Good question!
Based on (1) common discussions from fans; and (2) some former K-pop idols who had a chance to try the P-pop idol industry; yes.
The Department of Labour and Employment is active in protecting the workforce. And the Philippine Labour Laws were made to protect and side with the labourer, not the employers.
For example, if there is a stipulation in the contract that places the labourer at a disadvantage and/or is against the labour code, the contract is null and void.
They also are not asked to surrender their phones, or to stay at dorms 24/7. They do are constantly reminded what they can and cannot do, especially with their online accounts. Their personal accounts remain theirs, employers cannot ask for access. However, they can agree that the personal account won't be used because they'll create a promotion account and their manager will manage it; until such a time they can be trusted not to make a mistake.
If they can come to trainings without being late, they can live elsewhere. Otherwise, they can choose to stay at a provided place.
At least those are the ones I'm familiar with. Basically, P-pop idols are under the same labour laws and practices first; any other specific conditions are added on top of that.
