Dear Khun Nattapong,
Your request highly supported. My prime concern today was Safety which I fail to get positive input from my lead. I wish my team to work safely and complete the job with Respect to your Project Schedule.
I'm worried since there's no want speak about Safety arrangement at night and there are some interested demanding 1/2 hours with me. Like I said to them before, they can continue if need to finish and inform me. That's fine for me.
I wish this time you personally advice & ensure the lighting visibility are sufficient for my team to perform safely.
