Dream Sports, a Mumbai-based tech company that runs fantasy sports platform Dream11, told CNBC in an interview published on December 26 that it requires its employees to take a week off and "unplug" from the company's system every year.That helps the employee on vacation to have a week of uninterrupted break, and it also "helps the business to know whether we're dependent on anyone," he said."No one wants to be that jerk who called someone who was on unplug," COO and co-founder Bhavit Sheth told CNBC.The startup's policy echoes similar ones by larger companies to encourage staff to take time off work, amid a tight labor market.In the same month, Goldman Sachs implemented a scheme that allows senior bankers to take an unlimited number of vacation days."
