W: Working for four hours at a stretch really makes me tired. Why can’t we have a break like many other companies? We need at least a tea break.
M:(13)Our boss is dead nuts on work. Keeping on working and making money is what he has in his mind. Nothing else.
W: But we workers need rest.
M: Actually in some other companies they also have the exercise to the radio broadcast. We need relaxation once in a while and only in this way can we work efficiently.
W: About the exercise to the radio broadcast, it’s been quite a long time since I last did in the secondary school. It felt really good to exercise a bit after two hours’ lecture.
M: We also did that in the company I worked with before I moved here.(14)The department head of ours has been a real health nut ever since he quit smoking. I have to hand it to him, though. He never was a great worker, but he was sure to turn into a good athlete.
W: At least we’ll be able to take off a few pounds with the exercise every day.
M: Did they tell you about the thing we’ll do tomorrow?
W: What? No one told me anything.
M:(15)The company’s holding its annual employment test tomorrow.
W: Don’t tell me we have to work tomorrow!
M: I’m afraid we have to come. At 8 o’clock sharp.
