Could manager’s telecommuting ban be bias?

Q. We have a bunch of employees who telework. One manager wants to follow the approach Yahoo took last year and eliminate teleworking. He believes that employees are not actually working and that their inability to see the whites of each other’s eyes is limiting their collaboration. He’s made some comments in the past that make me think he really worries that female employees are spending work time caring for their children from home. What should we do?
