    In our new hybrid work reality, many people in IT have enjoyed the flexibility to rewrite the rules on work-life balance. But it’s been a learning curve, says Kumud Kalia, CIO, Guardant Health.

    “As we moved to remote working for most of our employees, it became evident that time management had become much more of a juggling act between work, childcare/schooling, and miscellaneous personal priorities without a clear separation between these various activities.
