請問此句英文怎麼說?

If it is only for one person, I prefer to use "absent from work". If it is for a group of people, I prefer unsing "industrial strike".

absent from work without prior notice
absent from work without permission granted

曠工= absent from work without prior permission
= strike/ on strike

industrial action
係勞工行動
尤指罷工
action that works take, especially stopping work, to protest to their employers about sth
佢話係去抗議僱主一d野
