Ni normal ke?

Hi, aku sekarang kerja kat satu company besar ni, electric shop, just nak tanya ni normal ke? X pernah kerja gini so nak tanya dulu.

1. dalam iklan tulis 5 hari kerja, 2 hri cuti, but end up 6 hari kerja, which 1 hari callback (used to be optional but not anymore, at least in most days)
2. Callback bayar rm80/hari, so satu bulan 4 hari
3. Kerja 10-9, callback 12-9. Total working hours 45 jam (w/out callback), 53 jam (with callback)

Is this normal working hours for you guys too?
