House Keeping Schedule - issues like Timings, Unplanned work on our R&R Implementation

Dear Experts, In My Working Factory, having 5 women housekeepers. They are good workers.
We planned to Prepare roles and responsibilities for each one. We face some kind of issues like Timings, Unplanned work on our R&R Implementation. Moreover, we don't want to lose those good employees. Kindly share with me what kind of responsibilities of HK used at your end and support me to solve those issues.

Enforcing discipline in work places is the tough task for any HR Dept. And now a days HK are outsourced increasingly. This type of work sharing eases the burden on HR personnel. Any difficulties in enforcing quality work and timeliness should be prioritized and problems faced should be sorted out by discussing with the service providers instantly. If necessary 'right person for right job' should ease the problems faced. The responsibilities allocation should depend on listing out HR activities vs resources on hand basis.

Dear Kumar,
Greetings of the day,
