Ano ba pwede kong gamitin na excuse?

Hi! I’m currently working on my first ever nursing job for 1 month. Ngayon, bago lang nag text yung government hospital na for exam ako next week. Sadly, may duty ako that time.

Ano ba pwede kong sabihin as excuse para makapag exam ako? Feel ko kasi ayaw talaga ako ng head nurse namin 😢 Sayang rin po kasi yung opportunity since I will be earning twice as much sa government hospital than my current workplace. 16k lang po yung salary ko currently and di po talaga ako mabubuhay sa salary especially since dami ko ring responsibilities as a breadwinner.
