Please help me to make the right choice in this sentence: He doesn't work / isn't working today because it's Sunday.
Are they both correct?
NOT A TEACHER
AT A RESTAURANT
Joe: Where is Mona, my favorite server (waitress)? I don't see her working.
Manager: She isn't working here today.
Joe: Why isn't she working here today?
Manager: Because it's Sunday. She doesn't work here on Sundays.
Joe: I didn't know that. Well, in that case, I am leaving.
Manager: Don't tell the owner that I told you, but Mona is working today at
that restaurant across the street.
Manager: Yeah. She works there on Sundays because the owner of that restaurant pays her more.
