We have two experienced HR managers who want to job-share our Head of People seat, working three days a week each. Can two people split one seat on the Accountability Chart if their combined schedule covers the full work week?

No. The rule on the Accountability Chart is absolute: only one name can occupy a single seat. When two people are accountable for a seat, nobody is accountable. If payroll processing fails or a compliance deadline is missed, who gets fired? In a co-ownership or job-sharing arrangement, each person invariably points to the other when results slip.

Job sharing can work for task execution, but it cannot exist at the accountability level. To solve this, you must decide which of the two individuals owns the seat. That person holds sole accountability for the five core roles, reports to the Integrator, owns the Scorecard measurables, and answers for quarterly Rocks.

The second manager can then be positioned directly underneath that seat, handling assigned execution, or placed in a specialized role such as Talent Acquisition Specialist or HR Operations Lead. Both individuals may negotiate part-time work arrangements or divide tactical hours behind the scenes, but only one human being sits in the box on the chart. That individual carries the weight of the outcomes. Structure comes first, people second.
