Hi! Sorry for sounding dumb but I really need your opinion and advice. I am a newly hired hospital pharmacist and I start on May 11. However, prior to applying, my friends and I already booked tix for daniel’s concert on may 21 (im not from mnl so technically 20-23) How do I ask permission regarding this one? Im really scared since this is my first job and I really want to sound respectful and professional as much as possible huhu
