Organisational Structures & Ways of Working

Human resources (HR) is the business function that looks after people — recruiting them, organising them, motivating them and developing them. Every business, from a two-person coffee van to a supermarket chain, needs some way of showing who reports to whom and how people are employed. This lesson covers two specification topics: organisational structures (tall and flat, plus matrix as a third type you may meet) and ways of working (full-time, part-time, flexible, temporary, working from home, working whilst mobile and self-employed).

Why Structure Matters

An organisational structure sets out job roles, responsibilities and lines of communication. It decides how quickly an instruction travels, who is allowed to make which decision, and how many people each manager supervises. Get it right and the business runs smoothly; get it wrong and instructions get lost, staff feel unclear on their role, and decisions take far too long.

Tall (Hierarchical) Structures

A tall structure has many layers of management. An NHS hospital trust is a clear example: a chief executive sits above directors, who sit above senior managers, ward managers and clinical staff. Each manager oversees only a handful of people, which means tight supervision and clear promotion paths — but decisions are slow because a message has to climb many rungs. Large, safety-critical organisations like the Royal Navy, the NHS and national banks tend to be tall because clear lines of responsibility matter more than speed.

Flat Structures

A flat structure has few layers. A tech start-up of twenty people might have a founder, one team of engineers and one team of marketers — that is it. Decisions happen fast, staff feel trusted and costs are lower because there are fewer managers to pay. The trade-off is that each manager supervises a lot of people, so they cannot give much individual attention. Start-ups and creative agencies usually run flat; they add layers as they grow.

Matrix Structures

A matrix structure mixes two reporting lines. An engineer at an engineering firm might report to both the ‘engineering department’ manager AND the manager of the specific project they are working on at the moment. This works well for businesses where project teams form and re-form — construction, consultancy, pharmaceuticals. Staff get the benefit of expert function managers plus hands-on project leadership. The risk is that two managers may pull in different directions, so clear rules on who decides what are essential.

Span of Control and Chain of Command

The span of control is the number of people a single manager oversees. A narrow span (three or four staff) allows close mentoring; a wide span (fifteen or more) demands that workers manage themselves. The chain of command is the route an instruction travels from the top of the business to the bottom. A long chain means careful control; a short chain means fewer people reword the message, so it arrives clearly.

Delegation, Subordinates and Authority

Delegation is when a manager hands a task, and the authority to complete it, to a subordinate further down the chain. A supermarket duty manager might delegate a promotional display to a supervisor. Good delegation motivates staff by showing trust, develops skills and frees managers for bigger decisions. Poor delegation — giving someone a task without the authority to decide, or without proper training — causes mistakes and resentment. The manager stays accountable even after delegating; handing the task over is not the same as handing over the responsibility.

Ways of Working

Once the business has a shape, it also has choices about how people are actually employed. OCR names several ways of working that have become common in UK businesses.

• Full-time — usually 35 to 40 hours a week. Gives the business a committed worker and the employee a stable income and holiday pay. Used for most core roles at M&S and Tesco.
• Part-time — fewer hours, often pro-rata pay and benefits. Helps parents, students and carers stay in work and helps businesses match staffing to demand — a café can run three staff at lunchtime and one mid-afternoon.
• Temporary — a fixed-term or casual arrangement, common at Christmas (Royal Mail hires thousands of seasonal sorters) or during exam marking.
• Working whilst mobile — the job is done on the move using a phone, tablet or van: delivery drivers, sales reps and engineers travelling between customer sites. A related arrangement is the zero-hour contract, where no hours are guaranteed and workers are called in as needed — common in hospitality and retail.
• Flexible working — staggered hours, compressed weeks, or flexi-time. Helps staff balance work and life, which can improve retention.
• Working from home / remote working — the employee does the job from home or another location, using a laptop and internet. Exploded in use after 2020. Cuts commuting and can cut office rent, but makes teamwork and training harder.
• Self-employed — the worker is their own boss (a freelance designer, a plumber, a market trader). Not an employee of the business at all — hired for specific jobs and paid per invoice.
