We have two highly competent customer service managers who want to job-share a single department head seat on our Accountability Chart, working part-time. They are both stellar performers, so why can we not put both names in that single seat?

The short answer is absolutely not. Putting two names in a single seat on your Accountability Chart is an operational disaster. It completely violates the core EOS® principle of having one name accountable per seat.

When two people share responsibility for a seat, no one is actually responsible. Accountability is binary: it is either on one person, or it is lost. If an issue arises or a target is missed, the two co-leaders will inevitably point fingers at each other, or the team will get conflicting directions.

This rule applies to all levels of the organization, including job-sharing arrangements. If you have two part-time employees handling customer service, they do not share the customer service manager seat. Instead, you must structure the chart so that one person is ultimately accountable for the department seat, and the other reports to them, or you must split the territory or functions into two distinct seats.

A potential buyer looking at your business will instantly see shared seats as a major risk. They want to see a clean, clear reporting structure where every single function has a single point of contact who owns the outcomes.

If you want to protect your operations and build real enterprise value, you must make a hard choice. Define the seat, choose the single best person to own the accountability, and have the other support them in a clearly defined subordinate role.
