Two thirds of employees either eat lunch at their desk or take no lunch at all, according to a survey by Right Management, a ManpowerGroup Inc. (NYSE: MAN) company.

One third of employees, or 34 percent, said they take a break for lunch, but eat it at their desks. Fifteen percent said they take a break from time to time, while another 16 percent said they seldom do. Only 35 percent said they regularly take a break for lunch.

The workplace culture or management’s example might make workers feel compelled to stay at their desks, observed Michael Haid, senior vice president talent management at Right Management. “Employees may feel they have to apologize for stepping out, but in the long run this kind of company culture does not help improve performance or engagement,” he said.

Right Management polled 751 North American workers online in July and August.
