thought u have some good practice to share on how to cancel night shift at last minute.
because yesterday morning, my experience was ...to divert you all from BPK to KT (8 managers including jiraporn), it took me 15 minutes of calling / SMS & using "line".
so u mean from below : your original schedule was no night shift last night, which u already told your team a day before, so no last minute call-tree.
