W: No, what’s up?
M: I just heard that the company is planning to fire 20 percent of the workers in the next two months.
W: You’re joking. I knew they were looking for some way to cut costs this season, but I didn’t think that they would fire any workers.
M: Yeah, it’s hard to believe. That’ll be hundreds of people losing their jobs. It’s not just the salary. You know, I hope it’s not going to be Mike. With three kids and a wife who’s sick, that would really be a blow.
W: When will we know who is getting fired?
