Founder Insights
I’m Fred Thompson, CEO of Thirst. A few months ago, one of our best managers went on leave for three weeks, and onboarding for two new hires quietly ground to a halt. Nobody did anything wrong. That’s exactly the problem.
When I dug into why, I went in expecting to find a manager who hadn’t prioritised handovers, or a process that had simply been skipped in the rush of a busy quarter. What I found instead was a system that had never actually worked without her in the room. Every “onboarding process” we had on paper turned out to be a set of instructions for how she onboarded people — not a process at all. Take her out of the picture, even briefly, and there was nothing underneath.
When onboarding only works if the right person is free
Most businesses would say their onboarding is a process. In practice, for a huge number of them, it’s a person. It’s whichever manager happens to be free that week, willing to run through the same fifteen things they’ve explained a dozen times before, from memory, in whatever order occurs to them on the day.
That works fine when the manager has bandwidth. It falls apart the moment they don’t — a busy sprint, a big client pitch, parental leave, a resignation. New hires are left waiting on the one person who can answer their questions, and that person is exactly the person you can least afford to have distracted right now, because they’re also trying to run the team.
1:1 bottleneck
A new hire’s entire ramp-up runs through weekly check-ins with one manager, so progress can only ever move as fast as that manager’s calendar allows.
Tribal handoff
“Just ask your manager” becomes the answer to every question that isn’t in the (thin, outdated) onboarding doc — because the real answers were never written down anywhere else.
Shadow curriculum
Every manager onboards their own hires slightly differently, based on what they personally remember to cover — so quality of onboarding depends entirely on who a new hire happens to report to.
Manager dependency isn’t a character flaw
The instinct, when onboarding stalls, is to look for someone to fix. Maybe this manager needs coaching on delegation. Maybe they need to “make time” for it. I understand the instinct — I’ve had it myself. But blaming the manager mistakes a design flaw for a people problem, and design flaws don’t get fixed by asking individuals to try harder.
Good managers are, by definition, busy doing the job that makes them good managers. If the only path for a new hire to get context, answers, and confidence runs exclusively through that one person, you haven’t built an onboarding process — you’ve built a queue with a single server, and you’re surprised when it backs up. The fix isn’t a better manager. It’s a system that doesn’t collapse the moment one person is stretched thin.
Why it looks fine until someone’s calendar fills up
Manager-dependent onboarding is invisible on a normal week, for a few structural reasons:
Nobody measures onboarding capacity. We track headcount and hiring pipelines closely. We almost never ask whether the managers receiving those hires actually have room to onboard them well.
Good managers absorb the gap silently. The best managers will simply work later, or squeeze onboarding in around everything else, rather than let a new hire flounder — which quietly hides the problem instead of surfacing it.
New hires rarely complain, even when it’s not working. Someone three weeks into a new job isn’t going to raise their hand and say the onboarding is disorganised — they assume it’s just how things are done here, and adapt.
of employees, according to Gallup’s widely cited research on onboarding, strongly agree their organisation does a great job of it. The other 88% aren’t necessarily working somewhere with bad managers — many are working somewhere with no real system at all.
The cost nobody puts on a scorecard
When onboarding depends on one manager’s spare capacity, the cost doesn’t show up as a line item. It shows up as a slow leak, spread across three places:
Time-to-productivity stretches out. New hires wait on answers instead of getting them, so the gap between “hired” and “genuinely contributing” grows quietly wider than anyone budgeted for.
The manager’s own output takes the hit. Every hour spent re-explaining the basics from memory is an hour not spent on the work only they can do — and it recurs with every new hire, indefinitely.
Early impressions — and early exits — take shape. A confusing first few weeks is one of the most common reasons new hires disengage, or leave, before they’ve had a real chance to settle in.
new hires, in industry onboarding research, say they’ve considered leaving a job within the first week because of a poor onboarding experience — long before the role itself was ever really given a fair chance.
Where I got this wrong first
For a long time, our answer to “onboarding isn’t working” was to write a better checklist and hand it to managers. New checklist, same fundamental design: it still assumed a manager would sit down, walk through it in person, and personally answer whatever wasn’t covered. We’d just made the queue a bit tidier — we hadn’t added a second server.
It took that three-week gap in cover to make the flaw obvious. The checklist wasn’t the problem. The fact that everything on it depended on one specific person being available was the problem. Once I saw it that way, I stopped asking “how do we get managers to onboard better” and started asking “how do we make onboarding not require a manager to be free.”
What actually fixes it
This isn’t about removing managers from onboarding — their judgement and context still matter enormously. It’s about making sure they’re not the only path to it.
Separate context from access
Most of what a manager repeats in every onboarding conversation is context, not judgement. Context can be captured once and reused endlessly. Save the manager’s time for the handful of things that genuinely need their input.
Give new hires somewhere else to look first
“Ask your manager” should be the fallback, not the default. If a new hire can find a good answer themselves, they build confidence and move faster — and the manager only gets pulled in for what genuinely needs them.
Design for the manager who’s stretched, not the one with a free week
If your onboarding only works when a manager has spare capacity, it will fail exactly when you need it most — during growth, during turnover, during the busiest quarters. Build for the average week, not the ideal one.
This is exactly the gap we’ve tried to close with Thirst — giving new hires a structured, searchable place to find answers on their own, so managers stop being the single point of failure in their own team’s onboarding.

What good onboarding without a bottleneck looks like
The difference isn’t dramatic day to day. It shows up in a lot of small things adding up:
Speed
New hires get unblocked in minutes instead of waiting for their manager’s next free slot.
Consistency
Every new hire gets the same quality of onboarding, regardless of which manager they happen to report to.
Manager time back
Managers spend their onboarding time on judgement and relationship-building, not repeating the same basics from memory.
Resilience
A manager going on leave, changing teams, or moving on doesn’t put onboarding on hold for whoever’s hired next.
That’s the real shift — from onboarding being something a manager personally delivers, to something the business reliably provides, with the manager as one important part of it rather than the whole of it.
I still catch us building manager-dependent habits sometimes. Old patterns are sticky. But I no longer mistake a stretched manager for a broken hire, or a broken hire for a bad manager. Most of the time, it’s just a system that was never built to survive a busy week — and that’s a fixable design problem, not a verdict on anyone’s character.
