You need to look at your "Table A" hours and also add "Day Tot" if your school has Before and after, Hubs or Daycares and that is the minimum hours your school must have per week.
Every school is above "Table A" but don't forget your Daycare hours.
If they only provide enough hours for Table A, your efforts should be to the school. Students are our customers and not the Daycare. The Board has commitments to daycares and so they should staff accordingly.
