We are an active and busy family of 5 (2 parents, 3 kids).
Our kids are 12, 10 and 8 yrs of age. They're happy, active kids.
We are looking for someone to help us 3 afternoons per week (Tuesday, Wednesday and Thursdays).
Responsibilities include:
? Laundry
? Bed linen changes
? Some meal preparation
? Driving kids to after school activities
? Homework, able to assist with Maths at a minimum.
? Making sure they do their chores.
Total hrs - approx 15 hrs per week (2pm to 6pm approx)
You will need to have your own car, as a big part of the job is driving our kids to their respective sports activities.
We will pay mileage rate for car usage over and above the hourly rate.
Looking for someone positive, kind, reliable with prior experience and references.
Pay will be $28-$30 per hr depending on experience and suitability. Paid weekly.
