M: Thanks for joining us today, Janis. How are you?
W: Great, thanks.
M: I know that our readers are very interested in hearing your thoughts on the workplace of the future. What do you think it will be like?
W: You know, there are several trends happening today that I believe will be the norm of the future workplace.
M: How about sharing the top two with us?
W: Okay. First, I believe that telecommuting will replace the daily commute to an office. I think that more people will work regularly from home.
M: Interesting. Why is telecommuting so high on your list?
W: Thanks to the Internet, laptop computers, cell phones, and e-mail, I believe that more companies will encourage employees to work from home in the future. The fact is, people often get more done at home than they do in an office environment.
M: I completely agree. So, what's number two on the list?
W: In the future, I think the 9:00 to 5:00 workday will disappear.
M: You mean people won't be working during those hours.
W: No, I mean people will choose their own hours; the workday won't just be from 9:00 to 5:00. People will focus more on completing a project and will work the hours necessary to finish their work. So, some people will work from 8:00 to 4:00 and others from 1:00 to 9:00.
