A PRT* should be of 18 years minimum and should be working maximum 10 hours in a day. Derogation can be given to PRT whose age is in between 15 and 18 years old, with the written authorisation of their wali/parents but they should not be working more than 4 hours a day and should be given time for school/belajar. The later is a mandatory provision.
Any PRT should be entitle to 1 full month of salary as THR. Any PRT should be authorised one day off minimum per week and at least 12 days off per year (on top of the weekly rest of course).
Time should be given for prayer and other religious obligation.
The supervisation and enforcement of the rules will be done by Nakertrans, but also by the Pak lurah/kepala desa/pak RT with the power of inflicting administrative sanction.
It's obvious that the law will be enforced selectively. nakertrans is certainly not gonna be interested to check if all stipulations are respected in villages among families which aren't assumed wealthy. However, if you live in the same town than nakertrans office, if you are assumed to be wealthy (don't worry, if you are expat couple, a mixed indo/expat couple or an indonesian of chinese descent family, you ARE assumed to be wealthy ), nakertrans may be interested to check if you comply with the law.
*Are considered PRT, not only the maids. The tukang kebun, driver, private satpam, nurses...etc are included in the law.
