Nonverbal communication is very important in the work industry. Dealing with some customers is very difficult on a daily basis. You have some customers that come in with a attitude and has had a bad day. With seeing them having a bad day, you try your best not to say anything wrong. In the work industry, your coworkers mood can change as well. You can come to work and see your coworker upset or having a certain look on there face. You can tell by the look on there face that they are either upset or sad about something.
For example, I was working at Wal-mart for about 4 months. In those 4 months, I came across some coworkers that had bad moods at work but they weren't saying anything. Some of my coworkers were going through tough times that showed on there faces everyday.
My coworker Jake was having a bad day at work. You can tell he was having a bad day at work because of his mood and his attitude. I asked him what was wrong because he was going off on some employee's and some customers. His brother died in car accident and that's why he was sad and a little upset.
