It’s a common mandate in high volume manufacturing here in the US. It includes all time except for breaks.

I worked at a place that manufactured avionics boxes and most of the assembly line were super sweet little old Vietnamese ladies. The line supervisor was an old bat white lady-- a total Karen.

One day during our morning standup, they reinforced that it’s an English-only workplace. About an hour later, a few of the ladies were joking around in English and Karen, in her typical patronizing fake-sweet voice, reminded them that looks this is an English-only workplace. I butted in, loudly, “Karen, they ARE speaking English, you just can’t understand them.” The entire line erupted haha. Karen had her tail between her legs after that.

The Vietnamese ladies would always brought in good ass home-cooked lunch and have a little potluck. Every. Single. Day. They invited me to eat with them after every day after that. It was awesome. I even brought in homemade American food to share, which they actually liked and appreciated. It felt good. I miss those sweet old ladies. They were so fun to be around.
