More than half of workers, 59%, believe the 9-to-5 work day is a thing of the past, according to a survey of 3,244 full-time US workers by CareerBuilder.

Older workers more likely viewed the traditional eight-hour work day as a thing of the past. Among workers ages 45 to 54, the survey found that 65% believed the eight-hour work day was history. For workers ages 55 and older, 61% said the same.

However, for workers ages 18 to 24, the survey found only 42% believe the eight-hour work day is in the past.

CareerBuilder’s survey also found that 45% of all workers said they completed work outside of office hours, and 49% said they check or answer emails when they leave work.

“While smartphones and other technology allow us to remain connected to the office out of normal business hours, it may not always be a good thing as workers are having trouble disconnecting from their jobs,” said Rosemary Haefner, chief human resources officer for CareerBuilder.
