Hi
I did you request.
I calculate Qty Booking divided by rate 1:12. AFter that, The result show me how many personal You need per shift. And then, I add to cover the minimum personal per shift to cover the inside and outside.
Third point, I defined how many personal you need in full time and part time per day.
Finally, I displayed the type of shift to cover all of them.
I am expert in improve the process and reduce the costs.
Let me know , You are interest.
Thanks
