The first sign that informal HR has stopped working is usually not a crisis. It is a delay everyone has learned to tolerate.

A role stays open longer than expected. A manager interviews candidates without a clear scorecard. A new hire starts without a consistent onboarding plan. A people issue gets passed between leadership, operations, and HR because no one is quite sure who owns it.

The company is still functioning, but the system behind the work is starting to strain.

For many growing companies, this is the uncomfortable middle stage. The business is no longer small enough to run on founder judgment, manager instinct, and informal communication. But it may not yet be large enough to justify a deep HR department, specialized people operations team, or full-time senior HR leader.

That is the moment informal HR stops working.

Not because the team failed. Not because leadership ignored people. Usually, the opposite is true. The company got this far because people moved fast, solved problems directly, and avoided unnecessary bureaucracy.

But the same habits that help a company grow from 10 to 50 employees often start breaking down somewhere between 50 and 100. By the time the company reaches 150 or 250 employees, those small gaps can become recurring operating problems.

What It Usually Looks Like

It usually looks something like this.

The founder still gets pulled into people decisions that should no longer require founder involvement. The COO is quietly becoming the backstop for hiring process problems, onboarding gaps, manager confusion, and internal communication issues. HR is expected to be responsive, strategic, administrative, supportive, compliant, and fast — often with less capacity than the business actually needs.

Managers do their best, but each one handles people decisions differently.

One manager is structured and communicative. Another waits too long to give feedback. A third improvises interviews based on gut instinct. A fourth avoids difficult conversations until the problem becomes harder to fix.

Hiring still happens, but inconsistently. Onboarding still happens, but differently depending on the team. Policies may exist, but process ownership is unclear. Expectations are understood by some people and assumed by others.

No single issue feels catastrophic. That is what makes the problem easy to underestimate.

Informal HR rarely fails all at once. It creates drag.

The Real Problem Is Usually Not “HR”

When leaders hear “HR problem,” they often think of policies, compliance, payroll, benefits, or employee relations.

Those things matter. But in a growing company, the earliest signs of HR strain often show up as operating problems:
 

• hiring takes too long,

• managers evaluate people inconsistently,

• new hires get different onboarding experiences,

• communication depends too much on individual effort,

• workforce planning is reactive,

• decision ownership is unclear,

• and leadership spends too much time resolving avoidable friction.
   

This is why informal HR becomes expensive before it becomes obvious.

The business may not feel “broken.” It may simply feel harder to run than it should.

The founder is still involved in too many decisions. The COO is absorbing too many process gaps. HR is handling too much reactive work. Managers are carrying people responsibilities without enough structure. Employees notice inconsistency, even if they do not always name it directly.

At this stage, the issue is not whether the company cares about people.

The issue is whether the company has built the operating structure required to support them.

Why the Cost of Doing Nothing Adds Up

The cost of informal HR shows up in several places at once.

Turnover gets more expensive.

When people leave, the cost is rarely limited to recruiting fees or job ads.

There is lost productivity, manager time, training time, institutional knowledge, disruption to the team, and the opportunity cost of replacing someone who already understood the business. SHRM has cited replacement costs ranging from 50% to 200% of an employee’s annual salary, depending on role level and complexity.

That range should get the attention of any founder or COO. If a company is losing people because onboarding is inconsistent, managers are unsupported, expectations are unclear, or career paths are invisible, the cost is not abstract. It hits the business directly.

Managers absorb the gaps.

When HR structure is thin, managers become the operating layer between business goals and employee experience.

That can work for a while. But if managers are not given clear processes, expectations, tools, and decision frameworks, they end up improvising. They spend time solving avoidable problems, interpreting unclear policies, smoothing over communication issues, and carrying emotional weight that should be supported by better systems.

Gallup’s workplace research continues to show the importance of manager engagement and support. Manager engagement has declined in recent years, and Gallup’s reporting has connected manager strain to broader employee engagement and productivity challenges.

For growing companies, this matters because managers are often the first people asked to compensate for missing HR infrastructure. If they are not supported, the business does not just create manager burnout. It creates inconsistent execution.

Onboarding becomes a missed opportunity.

Onboarding is one of the clearest examples of informal HR strain.

A company may think onboarding is happening because new hires receive equipment, meet their team, and get access to systems. But operational onboarding is not the same as effective onboarding.

Effective onboarding helps a new employee understand the company, the role, the expectations, the team, the decision-making culture, and what success looks like. Gallup has reported that only a small percentage of employees strongly agree their organization does a great job of onboarding.

That is not just an HR statistic. It is a productivity issue.

When onboarding is inconsistent, new hires take longer to become effective. Managers spend more time repeating context. Early uncertainty increases. Expectations drift. The company may eventually correct the problem, but often after weeks or months of avoidable friction.

Engagement and productivity become harder to protect.

Employee engagement is often treated like a culture issue, but it is also an operating issue.

People are more likely to stay engaged when they understand what is expected of them, have the materials and support they need, receive useful feedback, trust their manager, and see how their work connects to the larger business. Those are not abstract cultural ideals. They are management and HR systems.

Gallup’s Q12 research has connected employee engagement with business outcomes across teams and organizations, including productivity, profitability, retention, absenteeism, and other performance indicators.

That matters for growing companies because informal HR systems often weaken exactly those conditions. Expectations become less clear. Manager support becomes uneven. Feedback quality varies. Hiring and onboarding inconsistencies create confusion. People do not always know where to go for answers.

Over time, the business pays for that ambiguity.

Four Signs Your Company Has Outgrown Informal HR

The transition point is not always obvious, but there are recurring signs.

1. Ownership is unclear.

If people frequently ask, “Who owns this?” the process probably needs structure.

This may show up in hiring, onboarding, employee questions, manager support, performance conversations, role changes, or workforce planning. When ownership is unclear, issues bounce between leaders, managers, HR, and operations until someone finally steps in.

That may work occasionally. It does not scale.

A growing company needs to define who owns which people processes, who makes which decisions, and when issues need to escalate.

2. Managers are making it up as they go.

Managers should have judgment. They should not have to invent the system.

If every manager interviews differently, gives feedback differently, documents differently, onboards differently, and handles employee issues differently, the company is not operating with flexibility. It is operating with inconsistency.

That inconsistency creates risk, slows decisions, weakens employee experience, and makes performance harder to manage.

The goal is not to turn managers into rule-followers. The goal is to give them enough structure to make better decisions.

3. Processes depend on memory and relationships.

In smaller companies, people often know who to ask, where to find things, and how decisions get made because they have been around long enough to absorb the informal system.

That creates a problem for new hires and new managers.

If the real process lives in people’s heads, the company becomes harder to join, harder to manage, and harder to scale. Documentation does not need to be excessive. But the core people processes should be clear enough that the company does not rely on tribal knowledge to function.

4. HR is always reacting.

Reactive HR is not a character flaw. It is often a capacity and structure problem.

When HR is constantly responding to urgent requests, it has less time to improve systems, support managers, plan workforce needs, improve onboarding, or address recurring root causes.

The result is a loop: the team is too busy reacting to fix the systems that are causing the reaction.

That loop is one of the clearest signs outside support may be useful.

What to Build Instead

The answer is not to overbuild HR.

Growing companies do not need to copy the structures of much larger organizations. They need practical people infrastructure that fits their stage.

A useful starting point is a staged diagnostic framework.

Step 1: Identify ownership.

Start with the recurring people processes that create the most friction:
 

• hiring,

• onboarding,

• manager support,

• employee questions,

• performance expectations,

• role changes,

• workforce planning,

• and internal communication.
   

For each one, ask:
 

• Who owns this?

• Who contributes to it?

• Who approves decisions?

• Where does the process begin and end?

• What happens when something falls outside the normal path?
   

If the answers are unclear, the process is probably being held together by effort rather than structure.

Step 2: Document the repeatable parts.

Documentation does not need to be long. It needs to be usable.

A growing company should have simple, accessible documentation for repeatable processes. That may include hiring intake steps, interview expectations, onboarding checklists, manager guidance, role-change workflows, or basic people-process ownership.

The goal is not paperwork.

The goal is consistency.

If a process happens repeatedly and affects employees, managers, candidates, or leadership decisions, it should not depend entirely on memory.

Step 3: Clarify manager responsibilities.

Managers are often the pressure point where informal HR breaks.

They need clarity on what they own, what HR owns, what leadership owns, and where they can go for support. This includes hiring participation, interview feedback, onboarding responsibilities, performance expectations, communication norms, and escalation paths.

When managers are supported, people processes improve. When they are left to improvise, inconsistency spreads.

Step 4: Decide where outside support makes sense.

Not every growing company needs a full-time senior HR hire right away.

But many need experienced support before they reach that point.

Outside HR and talent support can help identify the operating problem, build practical structure, support HR capacity, improve hiring workflows, strengthen onboarding, clarify manager responsibilities, and create systems that fit the company’s current stage.

The question is not always, “Do we need to hire someone full-time?”

Sometimes the better question is:

“What structure do we need now so the business can keep moving?”

Where HIP Fits

This is the kind of problem Higher Impact People was built to help with.

HIP works with growing companies that have outgrown informal hiring and people processes but may not need — or may not be ready for — another full-time hire. The work is focused on translating messy people issues into practical operating structure.

That may include HR operations support, hiring process improvement, workforce planning, onboarding structure, manager support, candidate experience, or flexible HR and talent capacity.

HIP is led by Nicholas Brandenburg, PHR, SHRM-CP, and is licensed, bonded, and insured in Massachusetts. The work brings together recruiting experience, HR knowledge, business advisory perspective, and a practical understanding of how people processes affect company execution.

The goal is not to add complexity.

The goal is to help the company see what is happening, clarify what needs to change, and build enough structure for the next stage of growth.

Schedule an Alignment Call
