How to Support Line Managers in a Small Business
Most line managers I've worked with didn't set out to manage people. They were good at their job, someone left or the business grew, and suddenly they had a team.
Nobody sat them down and explained what to do when someone keeps phoning in sick on a Monday, or when two people on the team stop speaking to each other. They just had to work it out.
In a bigger organisation, there's usually an HR team to ring. In a small business, there often isn't. So the manager either guesses, avoids it, or passes it straight up to the owner. None of those are great.
I've spent over 15 years in HR, and a lot of that time has been spent supporting line managers. This is what I've found actually helps.
Why line managers matter more than most people think
For most employees, their line manager is the business. They're the person who agrees their holiday, notices when something's wrong and has the awkward conversation when it needs to happen.
When managers handle things well, problems stay small. When they don't, a quiet word about timekeeping can turn into a grievance, a long-term absence or someone handing their notice in.
There's a legal side to this too. A lot of employment disputes start with something a manager said or did, or didn't do. With the Employment Rights Act 2025 bringing in changes like unfair dismissal rights after six months' employment from 1st January 2027, how your managers handle issues is going to matter even more.
The things managers struggle with most
In my experience, it's rarely the big, dramatic stuff. It's the everyday things:
Absence, especially short, frequent absences that don't quite add up
Performance that's slipped, but not badly enough to feel "formal"
Conduct issues, like lateness, attitude or phone use
Conflict between people in the team
Someone who's clearly struggling but hasn't said why
Knowing what they're allowed to say, and what they're not
Most of these start small. The problem is that managers often wait, hoping it'll sort itself out. By the time they ask for help, it's usually much harder to fix.
What good support for line managers looks like
You don't need a big training programme or a 40 page manager's handbook. For most small businesses, it comes down to a few simple things.
1. Someone to talk it through with
The most useful thing I've ever offered managers is a sounding board. Someone they can ring and say "this has happened, what should I do?" before they act.
Often they already know the answer. They just want to check it before they say something they can't take back. A ten minute conversation early on can save weeks of back and forth later.
2. Clear, simple processes
Managers need to know the process for the basics: reporting absence, holding a return to work meeting, raising a performance concern and handling a complaint.
That doesn't mean long policies. It means your staff handbook is up to date, and your managers actually know where to find it and what it says. If you're not sure yours is, my staff handbook checklist is a good place to start.
It also helps to agree a few basics across the business, so every manager handles things the same way. For example, everyone holds a short return to work chat after any sickness absence, and everyone knows who to tell when someone raises a concern.
3. Confidence with difficult conversations
Most managers aren't worried about the process. They're worried about the conversation itself. What if the person gets upset? What if they get angry? What if they say something unexpected?
A bit of preparation goes a long way. Before any tricky conversation, I'd encourage managers to think about:
What's the issue, in one or two sentences?
What examples do I have?
What do I want to happen next?
What might they say, and how will I respond?
It won't make the conversation easy, but it will make it clearer and fairer.
4. Knowing when to get advice
Managers should feel able to handle day to day issues themselves. But they also need to know when to stop and get advice. For example, if someone mentions a health condition, says they're being bullied or harassed, puts a complaint in writing, or if dismissal is on the table. If a formal complaint does come in, my guide on how to handle a grievance walks through it step by step.
A simple line in your handbook, or even a conversation at a team meeting, about when to ask for help can prevent a lot of problems.
5. Writing things down
I know, nobody likes paperwork. But a short note after an important conversation, saying what was discussed and what was agreed, is one of the best protections a manager has. It doesn't need to be formal. A quick email to the employee afterwards is often enough.
As a rule of thumb, I'd include the date, who was there, what was discussed, anything that was agreed and any next steps. That's it.
Mistakes I see small businesses make
Promoting someone and assuming they'll just pick it up
Only talking to managers about people issues when something has already gone wrong
The owner stepping in over the manager's head, which undermines them with the team
People being treated differently depending on who their manager is
Leaving managers to deal with really difficult situations on their own
None of these come from bad intentions. They usually happen because everyone's busy and the people side gets pushed down the list.
Where outside HR support fits in
Not every small business needs a full time HR person. But most do need someone their managers can turn to when things get tricky.
That's a big part of what I do. I act as a sounding board for managers, help them prepare for difficult conversations, and step in when something needs more formal handling. I can also run short, practical sessions for managers on the basics, like absence, performance and difficult conversations.
It also gives owners a bit of breathing space, as people issues stop landing on their desk by default.
If that sounds useful, have a look at my HR support services, or get in touch for an informal chat.
Where I've landed
Most managers want to do the right thing. They just need a bit of backup, and it helps if that backup is there before things go wrong, not after.
Frequently asked questions
What does a line manager do in HR terms?
They're usually responsible for the day to day people side of their team: approving leave, managing absence, setting expectations, giving feedback and dealing with early concerns about performance or conduct.
Do line managers need HR training?
Not formal qualifications, but they do need to understand the basics: your key policies, how to handle absence and performance, and when to ask for help. Short, practical sessions tend to work better than long courses.
What should a manager do if they're not sure how to handle an issue?
Pause and get advice before acting, especially if it involves health, discrimination, a formal complaint or possible dismissal. A quick check early on is far easier than fixing a mistake later.
Can an HR consultant support our managers without us hiring an HR person?
Yes. Many small businesses use an HR consultant as and when they need one, so managers have someone experienced to call on without the cost of a full time role.
