That's because labor laws here are very different from the States.

Doon, uso ang "immediate terminations". Lalapitan ka na lang ng security officers and escort you out the building. By then, disabled na lahat ng access mo (swipe cards, user accounts, etc). Syempre, depende sa company if they have that kind of capability. Yung mga naiwan mong gamit, ipapadala na lang nila yun sayo.

If they can let you go just like that, then conversely, you can also quit "just like that".

Dito generally, hindi pwede mga ganyan.
