Answer

He works "on the night shift". Please don't ask me why! It is just one of those quirks of the english language, I'm afraid.

Answer

Hi Thuy Duong,

We can simply write: "I am working the day shift." / "I worked the night shift last week." / "I clocked double shifts yesterday. I was so exhausted!"

There isn't a need to use a preposition in this case.

Hope this helps.
Cheers, Lance
