The traditional eight-hour work day may be on its way out, according to a survey by CareerBuilder.

The survey found 63% of workers in information technology, financial services, sales, and professional and business services — industries that historically have more traditional work hours — believe “working nine to five” is an outdated concept. And nearly one-quarter, 24%, check work emails during activities with family and friends.

Half of the workers surveyed said they check or respond to work emails outside of work, and 38% said they continue to work outside of office hours. However, 62% perceived staying connected to the office outside of required office hours as a choice rather than an obligation.

 “Workers want more flexibility in their schedules, and with improvements in technology that enable employees to check in at any time, from anywhere, it makes sense to allow employees to work outside the traditional nine-to-five schedule,” said Rosemary Haefner, chief human resources officer of CareerBuilder. “Moving away from a nine-to-five work week may not be possible for some companies (yet), but if done right, allowing employees more freedom and flexibility with their schedules can improve morale, boost productivity and increase retention rates.”

Male workers in these fields are more likely than female workers to work outside of office hours (44% versus 32%); check or respond to work emails outside of work (59% versus 42%) and check on work activities while they are out with friends and family (30% versus 18%). Female workers, however, are more likely than male workers to go to bed thinking about work (23% versus 16%).

When it comes to working outside of traditional office hours, 31% of 18- to 24-year-old workers in these fields will work outside of office hours, compared to 50% of 45- to 54-year-old workers and 38% of workers ages 55 and above. Meanwhile, 52% of workers ages 18-24 check or respond to work emails outside of work, versus 46% of workers ages 55 and above.

Seventy percent of workers ages 55 and above in these fields reported they stay connected to the office by choice, compared to 56% of workers ages 18-24 who said the same.

The survey was conducted online by Harris Interactive on behalf of CareerBuilder among 1,078 employees in the IT, financial services, sales and professional and business services industries. The survey was conducted between May 14 and June 3, 2015.
