ARTISTIC DUO: Western Digital chief executive Roger Johnson and his wife Janice always work for charitable causes as a team, one reason he says he’s leaving the executive committee of the Orange County Performing Arts Center. . . . Johnson says he has “a fundamental disagreement” with what he considers its unwritten policy of not letting husbands and wives serve together. Johnson says it’s an amicable parting, but he’s switching to the Pacific Symphony board, where his wife has long been a member and they can serve together.
