Line managers own onboarding when three things are in place: they understand why it matters, they have a clear, simple way to do it, and someone notices when they do it well. Get those right and involvement follows. Skip them and no system, however good, will fix it.
You've built a great pre-boarding and onboarding process. Now you need your line managers to actually run with it. That's usually where it stalls. You'll have heard the objections: “no more systems,” “isn't this HR's job,” “I don't have time.” But manager involvement is one of the biggest levers on new hire engagement. Eli's client data shows it consistently: organisations with higher manager involvement see higher new hire engagement, full stop.
So what actually works?
Consult them before you build
Line managers are on the front line of onboarding, so bring them in before you finalise your process, not after. A short survey or a workshop, asking what slows them down and what would genuinely help, surfaces problems you won't see from HR. It also makes managers more likely to back a process they had a hand in shaping.
Communicate why it matters, not just what to do
A great onboarding process nobody knows about doesn't get used. Launch it properly, explain how it improves new hire performance, engagement and retention, not just what managers are expected to click through. An exec sponsor recording a short video explaining why this matters reinforces the message far more than an email from HR ever will.
Give them support and training, not just access
Don't assume managers know what good onboarding looks like. Whether that's a short training session, guidance on your intranet, or a dedicated platform like Eli, give them the tools to succeed, not just a login. Eli's video for Rolls-Royce, built to educate and engage their global line manager population, is a good example of what that support can look like in practice.
Give them a checklist, not a guessing game
A clear list of what's expected of a line manager when a new hire joins removes ambiguity. That can be as simple as a printed step-by-step list, or something more sophisticated, run through an onboarding system and tailored to each new starter, with automated reminders that keep both manager and new hire on track without anyone having to chase.
Automate and simplify wherever you can
Onboarding is a small part of a line manager's job, so the easier you make it, the more they'll do it. Eli's team dashboard prioritises tasks across every new hire a manager is responsible for, saving them time. The Slack integration goes further, letting managers connect with new starters, manage tasks and keep an eye on engagement and wellbeing, all without leaving Slack.
Put it in their performance plan
This is a bigger step, but linking onboarding quality, and specifically the new hire's experience, to a manager's performance plan changes the calculation. Onboarding stops being an add-on and becomes part of the job. Everyone benefits: managers are recognised for doing it well, new hires get a better start, and the business sees the return in performance.
Reward and celebrate it publicly
When a line manager does onboarding well, say so. Interview them, share what they did with other managers, and let the results speak for themselves. Recognition and incentive schemes keep onboarding visible and front of mind, rather than something that only gets attention when it goes wrong.
There's no single formula. Find the combination that fits your organisation, and don't let early resistance put you off. When Eli started working with GE HealthCare, fewer than 50% of line managers took ownership of onboarding. With training, a dedicated portal and checklist on Eli, plus regular communication from senior leaders, that figure has never dropped below 80% since. Other clients pushing above 80% (and in some cases 90%) include Arcus FM, A&M, USS and NatWest Group.
FAQs
Why is line manager involvement important in onboarding?
Line managers have more day-to-day contact with a new hire than anyone else in the business. Eli's client data shows organisations with higher manager involvement in onboarding see higher new hire engagement. Managers who own onboarding well tend to see their new hires perform faster and stay longer.
What are the best ways to get line managers to own onboarding?
Consult them when you design the process, communicate why it matters (not just what to do), give them proper support and training, provide a clear checklist, automate the admin wherever possible, link onboarding quality to performance plans, and recognise managers who do it well.
How do you get line managers to engage when they say they don't have time?
Remove friction rather than adding more asks. A simple checklist, automated reminders, and a dashboard that prioritises tasks across all their new hires (rather than a list per hire) cuts the time cost significantly. The goal is to make good onboarding the path of least resistance.
Does technology actually help with line manager engagement?
Yes, when it removes admin rather than adding it. Eli's team dashboard consolidates tasks across every new hire a manager is responsible for, and the Slack integration lets managers manage onboarding tasks and check engagement without leaving a tool they already use daily.
How long does it take to get line managers onboard with a new process?
It varies, but GE HealthCare moved from under 50% manager ownership to consistently above 80% through training, a dedicated portal and checklist, and ongoing senior leader communication. Sustained change, not a single announcement, is what shifts the number.
