Are smartphones making us smarter? Bosses are especially concerned about this at the workplace because people check their phones as often as 150 times a day–meaning we may be distracted more than 50% of the time at work and have lower productivity. However, our devices are good for relationship building, and having a good friend at work tends to extend an employee’s stay at a job. In addition, smartphone use helps ensure that the workday never really ends and work time can extend into evenings and weekends. This could be both good and bad news because long hours can translate into lower productivity and, eventually, illness.
