When a business is growing, HR often develops in stages.

In the early days, it may be handled by the founder, a director, an office manager or whoever has the best grip on the paperwork. As the team grows, the people issues become more regular, more sensitive and more time consuming. By the time a business reaches corporate scale, HR usually needs a far more structured approach, with policies, processes, reporting, training and specialist support.

The legal responsibilities do not wait until a business is “big enough” to have an HR department. Once you employ staff, you have duties around contracts, pay, working time, holiday, discrimination, health and safety, payroll, pensions and fair treatment at work.

The difference between a start-up, an SME and a corporate organisation is not whether HR matters. It is the level of structure, consistency and risk management required.

HR in a start-up

For start-ups, HR often feels like something that can wait.

The focus is usually on sales, cash flow, customers, funding, suppliers and getting the business moving. That is understandable, but it can also lead to common problems. People may be brought in without clear contracts. Job roles may change without proper documentation. Pay, hours, holiday and expectations may be agreed informally. Policies may be copied from somewhere else and left unread.

This can work for a short time, especially when the team is very small and everyone is communicating closely. The difficulty comes when the business starts to grow, pressure increases, or a disagreement arises.

At start-up stage, HR does not need to be complicated, but it does need to be clear. Employers should have the basics in place, including written terms, payroll and pension arrangements, right to work checks, holiday records, basic policies, health and safety considerations, and a fair process for handling concerns.

A good start-up HR approach should protect the business without slowing it down. The aim is not to create a large handbook for the sake of it. It is to make sure everyone understands where they stand.

HR in an SME

For SMEs, HR becomes less about setting up the basics and more about consistency.

This is the stage where businesses often start to feel the impact of not having proper processes. Managers may deal with situations differently. One employee may be allowed flexibility while another is refused. Performance issues may be tolerated for too long because nobody wants a difficult conversation. Sickness absence, conduct concerns, grievances, family leave, holiday calculations and working arrangements may all start to take up more management time.

At this point, “we’ll deal with it when it happens” becomes risky.

SMEs need HR support that helps them make decisions fairly and confidently. That usually means having clear policies, accurate records, manager guidance, consistent onboarding, documented performance conversations, compliant contracts and a process for dealing with disciplinary and grievance matters.

This is also where culture starts to matter more. A business can no longer rely on the founder personally setting the tone in every conversation. Employees need to understand how things are done, managers need to know what they can and cannot agree, and the business needs a sensible record of decisions.

For many SMEs, this is the point where external HR support becomes valuable. They may not need a full internal HR department, but they do need someone who can help them stay compliant, manage risk and deal with people issues before they become bigger problems.

HR in a corporate organisation

Corporate HR is usually more formal because the scale of risk is different.

Larger organisations tend to have more employees, more managers, more departments, more complex reporting lines and a greater need for standardisation. HR may involve specialist areas such as employee relations, recruitment, learning and development, reward, payroll, compliance, equality and diversity, wellbeing, internal communications and organisational change.

The challenge for corporate employers is not simply having policies. It is making sure those policies are applied properly across the organisation.

A corporate business may have an excellent handbook, but if managers are not trained to use it, problems still arise. Inconsistent decisions, poor record keeping, unclear communication and delays in dealing with issues can all create legal and operational risk.

Corporate HR also needs to support strategic planning. Workforce planning, succession, restructuring, employee engagement, management capability, pay structures, reporting and compliance monitoring all become more important as the organisation grows.

The common mistake: thinking HR is only needed when something goes wrong

One of the biggest HR mistakes employers make is waiting until there is a problem.

By the time a grievance, disciplinary issue, absence concern or employment dispute has reached crisis point, the lack of earlier structure often becomes clear. There may be missing records, unclear expectations, outdated policies or decisions that were made informally and are now difficult to justify.

Good HR is not just about dealing with problems. It helps prevent them.

For start-ups, that means getting the foundations right early. For SMEs, it means creating consistency and giving managers the confidence to act fairly. For corporates, it means making sure people processes are applied properly at scale.

What should employers review?

Whatever the size of the business, employers should regularly review whether their HR arrangements match where the business is now, not where it was two or three years ago.

Useful questions include:

• Does every employee have clear written terms?
• Are contracts and policies up to date?
• Are holiday, sickness and working time records accurate?
• Do managers know how to handle performance, conduct and absence issues?
• Are flexible working requests dealt with fairly?
• Are pay, payroll, pension and statutory leave processes properly managed?
• Are decisions documented?
• Would the business be able to show that it acted reasonably if challenged?

The answers to these questions will look different depending on the size and complexity of the organisation, but the principle is the same. HR should grow with the business.

What this means for employers

A start-up does not need the same HR structure as a corporate organisation. An SME does not need unnecessary layers of process that slows decisions down. But every employer needs clear, fair and legally sound people practices.

The businesses that manage HR well are usually not the ones with the longest policies. They are the ones that understand their responsibilities, keep proper records, train their managers and deal with people issues before they become avoidable disputes.

For Black Country businesses, the key is making sure HR grows with the business, rather than being patched together only when something goes wrong.

Why this catches employers out

There are plenty of bank holidays across 2026, which means the same questions will keep coming up for employers. What do you do with part time staff? What happens if someone does not usually work Mondays? How do you deal with holiday for people whose hours change from week to week?

This is where things can get messy. Not because the rules are impossible to understand, but because holiday arrangements are often badly worded in contracts, applied inconsistently, or based on a system nobody has reviewed for years.

A lot of people assume staff are automatically entitled to bank holidays off on top of their annual leave. That is not the case. Workers are entitled to 5.6 weeks of paid holiday each year. Bank holidays can be included within that entitlement, or an employer can choose to give them in addition. The important thing is what the contract says.

There is a real difference between 20 days plus bank holidays and 28 days including bank holidays. Those two arrangements are not the same, and if the wording is unclear, confusion usually follows quite quickly.

Part timers and bank holidays

The issue is often less about the bank holiday itself and more about whether the overall entitlement is fair.

Take a part timer who works Tuesday to Thursday. If most bank holidays fall on a Monday and the business closes on those days, a full timer may seem to get the benefit every time while the part timer gets very little. If holiday has not been calculated properly on a pro rata basis, that can cause problems.

Part time workers are still entitled to 5.6 weeks’ holiday, just reduced in line with the number of days or hours they work. So, for example, someone who works 3 days a week is entitled to 16.8 days’ holiday a year.

Where employers go wrong is treating bank holidays as though they only matter if they fall on a day the employee normally works. That can leave part time staff at a disadvantage if the arrangement is not backed up by a fair pro rata calculation overall. If full time staff receive the benefit of bank holidays through the way leave is structured, part time staff need an equivalent entitlement on a pro rata basis.

In many cases, hours work better than days. For staff with a fixed pattern, calculating holiday in days may be perfectly fine. But where someone works longer days, shorter days, compressed hours or a pattern that changes, using hours is often much easier and much fairer.

It also makes bank holidays easier to manage. If the business closes on a bank holiday and that employee would normally have worked 6 hours that day, you deduct 6 hours from their holiday balance. If they would not normally have worked that day, you would not deduct anything, but their annual entitlement still needs to have been set correctly in the first place.

Irregular hours and common mistakes

For workers whose hours vary, holiday calculations need more care. For leave years starting on or after 1 April 2024, irregular hours workers and part year workers generally accrue holiday at 12.07 per cent of the hours worked in each pay period.

So if someone works variable shifts each month, their entitlement should be based on the hours they have actually worked, not a rough estimate and not whatever was done for someone with a completely different pattern. This often applies to casual workers, zero hours staff and other workers whose hours are not fixed.

Even where entitlement has been worked out properly, employers still need to think about how holiday pay is calculated. If someone’s pay varies, holiday pay may need to reflect their average pay rather than just their basic hourly rate. That is especially important where overtime or variable shifts are part of normal earnings.

We still see the same issues coming up again and again. Contracts that are out of date or unclear. Payroll and managers applying different rules in practice. Part timers only getting bank holidays if they happen to be rostered on that day. Irregular hours staff being squeezed into a system designed for fixed hours employees. And sometimes the biggest problem is simply that nobody can clearly explain how the calculation works when an employee asks.

If the answer is vague, that is usually a sign the process needs looking at.

A good time to review it

With Easter, the May bank holidays and the summer bank holiday all coming round in 2026, this is a good point to review how holiday is being handled.

Check what contracts say about bank holidays, whether part time staff are receiving a fair pro rata entitlement, and whether holiday would be better tracked in hours rather than days. If you have staff with irregular hours, it is also worth checking that the accrual method and holiday pay calculation are up to date.

Holiday entitlement is one of those things that often gets left until someone queries it. By that point, it is usually more awkward than it needed to be. If you have part timers, variable hours staff or contracts that have not been reviewed for a while, now is a sensible time to check that everything stacks up before the busy run of bank holidays really kicks in.

Sickness absence has always been one of the trickiest areas for employers to manage. It sits at the crossroads of wellbeing, legal compliance and operational pressure, and when it is not handled consistently, it can quickly become a source of risk and frustration.

Recent changes to sickness absence and Statutory Sick Pay rules are intended to encourage earlier intervention and better support for employees. In practice, however, many employers are finding that expectations on them are increasing, while clarity on how to manage absence day to day is still lacking.

Why sickness absence is under the spotlight

There is a growing recognition that long term sickness absence benefits no one. Employees can become disconnected from work, while businesses struggle with reduced capacity, increased costs and uncertainty around next steps.

The direction of travel is clear. Employers are expected to engage earlier, communicate more clearly and take a more structured approach to managing absence. This means informal arrangements and ad hoc decision making are no longer enough.

What this means for employers

For employers, the biggest risk is not the sickness itself, but inconsistency. Treating similar cases differently, missing key conversations or failing to keep proper records can quickly lead to employee relations issues or legal exposure.

A clear absence management process helps by setting expectations from the start. Employees know what is required of them, managers know what steps to follow, and the business can demonstrate that it has acted fairly and reasonably.

Good absence management is not about being heavy handed. It is about early conversations, appropriate support and clear documentation. When done well, it can reduce absence levels, improve morale and give managers confidence when dealing with difficult situations.

Do your current processes still work?

Many businesses have absence policies that were written years ago and rarely looked at. Others rely on informal practices that exist only in people’s heads. With sickness rules evolving, now is a sensible time to review whether your current approach is still fit for purpose.

Ask yourself whether managers know when to hold return to work meetings, how to handle repeated short-term absence or when medical advice should be sought. If the answer is unclear, that is often a sign the process needs tightening up.
