Part 4: Who Else It Hits
Every driver has a first-order cost to the company and a second-order cost to the people around the role. The second order is rarely on anyone's dashboard.
Part 3 put a dollar figure on what each outcome costs the company that made the hire. But none of the three drivers stays contained to the person in the seat. A vacancy, a quota miss, or a fit failure radiates outward — to teammates, to the manager, to customers, and to whoever the company hires next.
This report is about that radius: who else pays, and what the published research says it costs them.
Who Pays That Isn't the Hire?
Every driver has a first-order cost to the company and a second-order cost to the people around the role. The second order is rarely on anyone's dashboard.
Whoever covers the gap
Teammates absorbing open territory work at reduced capacity, and the deals needing attention most are disproportionately at risk. An open sales-engineer seat cuts close efficiency an estimated 15–20% per AE across the pod.
Whoever depends on their number
A miss cascades into the team forecast it was counted into. Top SEs lift AE win rates 15–25%, and great front-line managers lift rep performance 15–20% — a below-caliber hire in either seat suppresses that uplift instead.
Everyone in the room
Managers lose 17–26% of their time to underperformers. Teams with a toxic member perform 30–40% worse, exposed employees are 8× more likely to burn out, and 25% take the frustration out on customers directly.
Who Actually Absorbs It
None of this appears on the underperforming hire's own line item. It shows up on everyone else's.
Teammates covering the territory
Teammates absorbing open territory during a vacancy operate at reduced capacity, and competitive deals requiring attention during the gap are disproportionately at risk. For a sales engineer's pod, that's an estimated $4,000–$8,000/day in deal-influence opportunity cost across the two AEs supported — well above the generic $500/day cross-industry productivity-loss baseline (Fueler.io).
The manager
17–26% of a manager's time goes to supervising a poorly performing employee — 17% per a Robert Half survey of 1,400+ CFOs, up to 26% in a separate Robert Half survey — a $46K–$70K a year swing in diverted productivity at a $270K AE-manager OTE. At the VP level, that diverted time falls to the CRO or CEO instead.
The rest of the team
95% of CFOs say a poor hire at least somewhat impacts team morale (Robert Half), and teams with one toxic member perform 30–40% worse (peer-reviewed 2006 study). Disengagement contagion runs $3,400 for every $10,000 of affected teammates' salary (McLean & Company). A separate Harvard Business School study of 60,000 workers across 11 firms found a $12,489 induced-turnover cost from a toxic hire alone — one narrow downstream effect, before morale damage, litigation exposure or productivity loss are even counted.
Customers and prospects
Deals in flight at the time of an exit get handed off mid-cycle — some are lost entirely. Client and prospect relationships damaged during a hire's tenure do not reset when they leave. Harvard Business School research puts a number on where that friction goes: 25% of employees exposed to workplace incivility take the frustration out on customers directly.
The next candidate pool
Employer brand damage in a tight AI talent market raises the cost of the next search — the same market-wide effect that makes a poorly-run process visible to the people a company most needs to hire next.
None of this appears on the underperforming hire's own line item. It shows up on everyone else's.
Three Documented Effects, None of Them on the Hire's Line
Each of these is a separately published finding measuring a different thing. They are shown together to give a sense of magnitude — not because they add up.
Read each row on its own terms: the share of a manager's time spent supervising a poor performer; how much worse a team performs with one toxic member; and the share of employees exposed to workplace incivility who take the frustration out on customers.

Every one of these second-order costs happens before a company has even started looking for a replacement. Part 5 — the last report in this series — prices out what happens next: what it actually costs to start over.
