Deadline: 21st Century Fox’s voluntary buyout program is moving to the next phase, with those tenured TV and film employees who had accepted the buyout offer by the Feb. 29 deadline entering a 45-day window to mull over and agree to the terms in the separation agreement and sign it. No departures are final yet as staffers don’t have to commit to the buyout until mid-April. Still, information has started to trickle out about long-time Fox executives who are taking the package.
