I got a couple of question regarding lunch. In a work enviroment, Japanese people use 昼食 or they actually use the word 昼休み or maybe the latter is more a scholastic terminology? And for overnight workers? I work overnight and I was telling a Japanese person something happened to my lunch break...I used 昼休み, but I was not sure if it was appropriate also due to the fact that it was at 2am.
Thank you.
