Childcare providers try to deal with vacancies on a 'best fit' principle, as it means juggling many considerations. There are many reasons why 'first come, first served' is problematical.
Let’s say Bobby Brown leaves, giving me a full time. I offer it to Susie Smith, who is at the top of the waiting list, first come, first served. She takes Monday, Tuesday, Wednesday.
Julie Jones is next on the list but is very disappointed because she wanted full time, which I can no longer offer.
Next up is Gary Green. He just wants Thursday, so he's happy.
Then I'm stuck because nobody wants the Friday. But what’s worse is that I've broken up a full time slot that I cannot possible piece together again unless the right three families all leave at the same time.
What is more, I have sacrificed the earning potential of that Friday slot, but my running costs are still the same. So I either lose money (50% of nurseries are already financially unviable in the long-term) or put my fees up, which parents won’t like.
The final straw...... Next day, the mother of Wendy White (a valued client) gives me notice because she's expecting again and can see that I clearly won’t be able to hold a place for her forthcoming baby because of how my waiting list system works. There's no point in her using two different childcare providers and I clearly don’t value her loyalty, prompt payments, etc. So she’s off to another nursery with Wendy plus the impending baby.
And that’s the simple version. Phew!
