Here’s a gem. A study by Mary Noon at the University of Iowa and Jennifer Glass at the University of Texas says that telecommuting allows employers to expand workdays and create an expectation that staff will be available in the evenings and over weekends (Via Harvard Business Review/Monthly Labour Review).
On a related note, 20% of parents with children aged 10 only see them properly once a week according to a study by the Family and Parenting Institute in the UK.
