Dear Suparang
I noted that you will work overtime and I agree to your calculation. However I need even more manpower for completion of the picking and packing operation. The reason is that your warehouse is closed many days and I aim that the shipments must leave before closing.
In order that we can advise our customers about shipping details we need to complete picking and packing operation by Tuesday 28th April Thai evening time. This means that we can inform our customers about shipping details same day Tuesday 28th April. Then they can agree with forwarding companies on Wednesday 29th April and pick up on Thursday 30th April. We need your cooperation in order this will succeed.
Please work out a plan and confirm back to me. Thank you.
