How Telecommuting Works
Telecommuting, which is growing in popularity, allows employees to avoid long commutes.
“Brring,” the alarm startles you out of a deep sleep. It’s 8 a.m. on Monday morning. Time to head to the office. You roll out of bed, brush your teeth and stumble your way to the kitchen to grab some coffee.
Moments later, you head to the office, still wearing your pajamas and fluffy slippers. Luckily for you, you don’t have to go far – you work at home. Telecommuting, or working at home, has grown in popularity over the last 20 years.
On an increasing basis, workers are saying “no” to long commutes and opting to work at home. In fact, the U.S. Census Bureau reports that the number of employees working from home grew by 23 percent from 1990 to 2000.
Telecommuting workers revel in making their own schedule – allowing them to schedule work around family and personal commitments. With the ready availability of technology tools, like the Internet and home computers, companies are more willing to let employees work from home.
