No matter what the time is, in a global economy, you are competing against the person who is always working. Also, people have different work rhythms. For those who like to work fast and intense on things, any downtime is seen as disruptive. Of course, the shortest part of any work day seems to be our breaks and lunch hours. Grasha says that's perfectly normal from a psychological point of view.
Most people socialize during lunch and breaks.
Lunch on the job is a great way to meet one's social needs and needs for recognition and attention. And, if it's a power lunch, then the chance to influence others becomes available. Unfortunately, that's why it can be so difficult to go back to work after lunch. WORK UC psychologist Anthony Grasha said his research has demonstrated that humans really do have a relatively short attention span. That not only impacts how we learn, but how we do our jobs.
