Hokkien definition for 'shit job'. It means unpleasant things to do or extra tasks not within your job scope which you have to clear.
Look at Jimmy, he is so nice that he is willing to help anyone that drops by his desk, he is our office's sai kang warrior.

This job has a lot of sai kang to do, I can't wait to quit.
