Spencer is the English service’s executive director of human resources and industrial relations. Boyce is the executive director of CBC Radio and audio.
CBC spokesman Chuck Thompson said the leaves of absence are related to the Jian Ghomeshi scandal but declined to offer specifics. The former host of CBC Radio's Q was fired from his job in October and is now facing criminal charges.
The leaves of absence were not taken voluntarily, Thompson said.
A note from Heather Conway, executive vice-president of English Services, sent to staff on Monday said the past couple of months "have been difficult for many people," but she provided scant details about the leave.
"As I’m sure you can also appreciate, we will not be making any further public comment about Todd or Chris or their leaves of absence at this time," the memo says.
Ghomeshi, who is facing criminal charges over allegations of sexual assault and choking, is also facing questions about his conduct inside the CBC workplace, where he has been accused of groping and harassment, as well as sexually aggressive and abusive behaviour.
CBC hired employment lawyer Janice Rubin to conduct an investigation into the corporation’s handling of the allegations against Ghomeshi.
The former radio host has denied wrongdoing and his lawyers have said he will plead not guilty to the charges against him.
