Is there a minimum time for shifts?

This depends if you are an independent contractor or engaged in an employment relationship with a care or support worker.
Care and support workers on the Mable platform who are independent contractors can select their own rates and hours, and therefore there is no minimum time for shifts.
However, please keep in mind that workers may be less willing to attend shorter shifts, or may charge more for each visit. It is best to speak to the individual care workers about your specific needs, so that you can agree arrangements that work for you both.
If you are in an employment relationship with the care or support worker, then you must comply with the provisions of the relevant award, which may stipulate minimum shift times. If you would like assistance clarifying this, please call the Customer Care Team on 1300 73 65 73.
