Getting the right people in the right jobs at the right time
Human resource management (HRM) is the strategic job of making sure a business always has the right number of people, with the right skills, in the right roles, at the right time — and of managing them from the day they arrive to the day they leave. It starts with planning the workforce and runs through recruiting, selecting, training, appraising and, when necessary, letting people go.
Think of HRM as running the squad for a football club across a whole season, not just picking today's eleven. The coaching staff forecast which positions will be short next year as players age or leave (workforce planning), decide whether to promote from the academy or buy from another club (internal versus external recruitment), trial and sign the best fit (selection), run pre-season and match-day drills to sharpen skills (induction and on/off-the-job training), review each player after matches (appraisal), and handle departures — releasing a player who breaks the rules (dismissal) is a completely different thing from cutting a position the club no longer needs (redundancy). A club that plans the squad wins the league; one that only reacts match by match gets relegated.

Human resource (workforce) planning
Human resource planning — also called workforce planning — is the process of forecasting how many employees a business will need, and with which skills, then comparing that with the labour it expects to have available. It has two sides. Forecasting the DEMAND for labour means estimating the number and type of workers required to meet planned output and objectives. Forecasting the SUPPLY of labour means estimating how many suitable workers the business can actually get — internally from its current staff (allowing for retirements, promotions and leavers) and externally from the labour market. Planning is simply about spotting the GAP between the two early enough to do something about it: recruit and train if demand outstrips supply, or restructure and make redundancies if supply outstrips demand. A business that plans is proactive; one that does not is left firefighting skills shortages or paying for staff it no longer needs.
Forecast demand for labour: how many workers, and with what skills, are needed for planned output and objectives — driven by growth, new products and new markets.
Forecast supply of labour: the workers available internally (current staff, minus expected leavers and retirements) and externally (the local, national and global labour market).
Identify the gap: demand greater than supply signals recruitment and training; supply greater than demand signals possible redundancies or redeployment.
Plan to close it: the whole point of workforce planning is to act early — recruit, train, redeploy or restructure before a shortage or surplus becomes a crisis.
Why a business's human resource needs change
Workforce needs are never static, because the world the business operates in keeps shifting. Four causes come up again and again in the syllabus. NEW MARKETS: expanding into new products or territories creates demand for extra staff, sometimes with new skills or languages. TECHNOLOGY AND AUTOMATION: machines, software and AI can replace routine roles (cutting demand for manual or clerical labour) while creating demand for technical and digital skills. CHANGING LABOUR MOBILITY: how freely workers can move between jobs, regions and countries — affected by migration rules, remote working and skills transferability — changes the supply of labour a business can tap. DEMOGRAPHIC CHANGE: shifts in the age, size and make-up of the population — an ageing workforce, a shrinking pool of young workers — alter both how many workers are available and what a business must offer to keep them.
New markets: entering new products or countries raises demand for labour, often with new skills or language needs.
Technology and automation: replaces routine manual and clerical roles (lowering demand for that labour) while raising demand for technical and digital skills.
Changing labour mobility: migration policy, remote working and transferable skills change how easily a business can recruit — altering the supply of labour.
Demographic change: an ageing population or fewer young workers shifts both the size and the shape of the available workforce.
Recruitment: internal versus external
Once workforce planning reveals a gap, recruitment is the process of attracting a pool of suitable candidates to fill it. The first strategic choice is whether to recruit internally or externally. Internal recruitment fills the role with someone already employed by the business. It is usually quicker and cheaper, motivates staff by offering progression, and is lower-risk because the candidate is a known quantity — but it brings in no new ideas and simply moves the vacancy elsewhere. External recruitment brings in a candidate from outside. It opens up a far wider talent pool and injects fresh skills, ideas and experience — but it is slower, more expensive and riskier because the person is unproven inside the organisation.
Internal recruitment: quicker, cheaper, motivating and lower-risk (candidate is known) — but adds no new ideas and leaves a knock-on vacancy.
External recruitment: wider talent pool and fresh skills and ideas — but slower, costlier and riskier because the candidate is unproven inside the business.
Selection: whichever route is used, selection then chooses the best candidate from the pool using screening, interviews, tests and assessment centres. Recruitment attracts; selection picks.
Training and appraisal
Getting people in is only the start; developing them is what turns a new hire into a productive, motivated employee. Training usually begins with INDUCTION — the introduction given to new starters covering the organisation, their role, colleagues, systems and health-and-safety rules — so they settle in and become productive quickly. Beyond induction, training is either ON-THE-JOB (learning by doing at the workplace, through shadowing, coaching or mentoring — cheap and directly relevant, but it ties up the trainer and can pass on bad habits) or OFF-THE-JOB (learning away from the workstation, on external courses or online — broader and delivered by specialists, but more expensive and sometimes less specific to the role). APPRAISAL then closes the loop: a formal, periodic review of performance against agreed objectives that gives feedback and informs decisions on further training, pay and promotion.
Induction: first training for new starters — organisation, role, people, systems and safety — so they become productive and feel settled quickly.
On-the-job training: learning by doing at work (shadowing, coaching, mentoring) — cheap and relevant, but reduces the trainer's output and can spread bad habits.
Off-the-job training: learning away from the workstation (courses, seminars, online) — specialist and broad, but more expensive and less job-specific.
Appraisal: periodic review of performance against objectives, feeding decisions on training, pay and promotion.
Dismissal versus redundancy
People also leave the business, and the syllabus is precise about two very different ways this happens. DISMISSAL is the termination of a contract because of the EMPLOYEE — misconduct (such as theft or repeated lateness), incompetence, or breach of contract. The person is the reason the job ends, and dismissal must normally follow a fair procedure or it becomes unfair dismissal. REDUNDANCY is the termination of employment because the JOB itself is no longer needed — through automation, restructuring, relocation or a fall in demand — and it happens through no fault of the employee. Because the position, not the person, has ceased to exist, redundant workers are usually entitled to consultation and redundancy pay. Confusing the two is one of the most common and most costly errors in Unit 2.
Dismissal: ends the contract because of the EMPLOYEE — misconduct, incompetence or breach of contract; the person is the reason.
Redundancy: ends employment because the JOB disappears — automation, restructuring, relocation or falling demand; no fault of the worker.
Why it matters: the cause differs, and so do the legal duties — redundancy usually brings consultation and redundancy pay; dismissal must follow a fair procedure to avoid being 'unfair'.
Labour turnover and its costs
Labour turnover measures the rate at which employees leave a business over a period, usually a year, as a percentage. A moderate level is healthy — it clears out persistent underperformers and brings in fresh skills — but a HIGH rate is a warning sign, often pointing to low morale, weak management or uncompetitive pay, and it carries real costs: the expense of recruiting and selecting replacements, the cost of inducting and training them, lost productivity while roles sit vacant or new staff get up to speed, and the loss of experience and knowledge that walks out of the door. A figure only means something in context — compare it with previous years, the industry average or local competitors before judging it high or low.
Labour turnover rate (%) =
Flexible, outsourced and gig workforces
Increasingly, businesses meet their labour needs without hiring permanent, full-time staff. A FLEXIBLE workforce uses part-time, temporary, seasonal or zero-hours contracts so staffing can scale up and down with demand. OUTSOURCING hands non-core work — payroll, IT support, call centres — to an outside provider, letting the firm concentrate on what it does best and convert fixed costs into variable ones. The GIG economy takes flexibility furthest: labour is bought task by task from self-employed freelancers, with no long-term commitment on either side. All three cut fixed labour costs and add agility, but the trade-offs are weaker loyalty and control, harder retention of skills and knowledge, and concerns over job security and the ethics of insecure work.
Common mistakes examiners penalise
Confusing dismissal with redundancy — dismissal is about the EMPLOYEE (misconduct or incompetence); redundancy is about the JOB disappearing through no fault of the worker. Swapping them shows the concept is not understood.
Claiming internal recruitment brings 'new ideas' — that is the strength of EXTERNAL recruitment. Internal recruitment's advantages are speed, cost, motivation and lower risk.
Mixing up on- and off-the-job training — on-the-job is at the workplace while doing the job; off-the-job is away from the workstation. Induction is the initial training for new starters, not a third alternative to these two.
Quoting a labour turnover figure with no context — a percentage means nothing until compared with previous years, the industry average or competitors; and remember not all turnover is bad.
Assuming high labour turnover is always harmful — moderate turnover removes poor performers and injects fresh skills; the problem is losing valuable staff at a high rate.
Listing factors or advantages without applying them — a bare list earns AO1 only; the marks climb when each point is developed and tied to the specific business in the question.
Model answer — marked the way our engine marks it
Business Management 2.1 is assessed against three objectives: AO1 rewards relevant knowledge and understanding, AO2 rewards applying that knowledge to the specific business in the question, and AO3 rewards analysis — developing a point through a chain of reasoning to its effect. In the analytic/points scheme each distinct valid point earns credit, but for an 'explain' command term the marks are reserved for DEVELOPED, APPLIED points, not bare definitions. Watch how the marks below attach to a concept that is named (AO1), applied to a business (AO2) and then followed through to its effect on HR needs (AO3).
Where this leads
This topic is the foundation of the whole HRM unit. Workforce planning and the factors that change HR needs feed directly into organisational structure and the reasons firms delayer, restructure or outsource; the recruitment, training and appraisal tools return in leadership, motivation and organisational culture; and the analysis of labour turnover and its costs underpins later questions on employer–employee relations. Master the habit built here — name the concept, apply it to the specific business, then develop its effect through a chain of reasoning — and you have the template that earns marks across every Unit 2 question.
Worked examples
See the formulas applied — reveal one step at a time, like the exam.
At the start of 2025, 'GreenLeaf Organics' had 150 employees. During the year, 25 employees left the company. After hiring replacements it ended the year with 170 employees. Calculate the labour turnover rate for GreenLeaf Organics for 2025.

Step 1 — find the average number of staff. Average staff = (staff at start + staff at end) / 2 = (150 + 170) / 2 = 320 / 2 = 160 employees.
Explain two factors that may cause a business's human resource needs to change. [6]
- 1
Model answer. One factor is technology and automation. Take a car manufacturer that installs robotic arms on its assembly line: the machines can now do the routine welding and fitting that manual workers used to perform. Because each robot replaces the output of several people, the business's demand for low-skilled manual labour falls, and it may need to make some assembly roles redundant. At the same time its human resource needs do not simply shrink — they change shape: it now needs a smaller number of higher-skilled technicians to programme and maintain the robots, so the firm must recruit or retrain staff with those digital and engineering skills. Automation therefore reduces the demand for one type of labour while raising the demand for another.
