3-2 Dressing for success Until recently， I had never thought about how important our work clothes are. However， this changed when I arrived for my first day of work at my new job. The first thing I noticed was that the receptionist was wearing jeans. Then I met my boss， who was wearing shorts and trainers. Most of my other colleagues were similarly dressed. At first， I felt happy to work in such a relaxed environment， but after a few days， I realized something. People were always checking their social media and eating food at their desks. One colleague even fell asleep sometimes. I am ambitious， and this wasn’t the way I wanted to work. Then I had an idea. I had read about how wearing smart clothes can make people work harder， and I wanted to see if it was true. I remembered that some workplaces let staff come to work in casual clothes on Fridays. I suggested to my boss that our workplace do the opposite， asking staff to dress smartly on Fridays. The first “dress smart” Friday my colleagues looked so smart! And guess what? They seemed to work harder too. Suddenly， it felt like that my workplace was a more energetic place to be. My colleagues noticed the difference—and so did my boss， because three Fridays later， she suggested staff come to work smartly dressed every day. Now my colleagues and I always dress smartly， and as a result， I think our team is happier and more productive.27. Why was the writer unhappy in her new workplace?
