Six steps in order: vacancy arises, write job description, advertise the job, shortlist applicants, interview and test, select and offer. At the advertising step the job can be filled internally from existing staff or externally from outside.
Recruitment runs through set stages, and the job can be filled internally or externally.

2.3.1 Recruitment and selection

Recruitment is attracting suitable people to apply for a vacancy. Selection is choosing between those who applied. Keep the two words apart in your answers.

Internal recruitment fills a vacancy from the existing workforce, for example promoting a team member. External recruitment fills it from outside the business.

Benefits Limitations
Internal Quicker and cheaper; the person’s record is known; shows staff promotion is possible Few applicants; no new ideas; the old job must now be filled
External Larger pool; new skills and fresh ideas Advertising and interviewing cost money and time; ability less certain; staff may feel overlooked

Methods. Recruitment routes include internal notices, adverts, job centres, agencies and recommendation. Selection tools include application forms or CVs, interviews, tests and references. Choose methods that fit the post.

Main stages. One standard sequence is shown below.

  1. Identify that a vacancy exists and what the job needs.
  2. Write a job description (what the post involves) and a person specification (the skills and qualities wanted).
  3. Advertise, internally, externally or both.
  4. Collect and shortlist applications against the person specification.
  5. Interview and test the shortlist, and take up references.
  6. Offer the post to the best candidate and agree the employment contract.
  7. Welcome the new starter with induction training.

Part-time and full-time employees. Part-timers work fewer hours than the business’s normal full week.

Benefits Limitations
Part-time Cover matches busy periods; wages paid only for hours needed; attracts people who cannot work full weeks More people to recruit, train and manage; harder communication across short shifts
Full-time Reliable cover; staff learn the job deeply; usually stronger loyalty Paid for the whole contract even in quiet spells; less flexible

Worked example. Thistlegate Bakery needs 30 hours of counter cover a week. A full-time contract is 40 hours at Rs 500 an hour. Two part-timers would each work 15 hours at the same rate.

  • Full-time cost: 40 × 500 = Rs 20,000 a week.
  • Part-time cost: 2 × 15 × 500 = Rs 15,000 a week.
  • Saving: 20,000 − 15,000 = Rs 5,000, which is 5,000 ÷ 20,000 = 25% of the full-time bill.
  • Offsetting cost: induction for two people at Rs 1,200 each is Rs 2,400 once. That is recovered in 2,400 ÷ 5,000 = 0.48 of a week.

Judgement: part-time is cheaper, but the bakery must weigh extra management effort and cover gaps if one part-timer is absent.

Recommend and justify who to employ. You will be given two or three candidates and a business situation. Match each candidate against what this business needs now. State your choice, give two reasons tied to the facts, then say why the runner-up was less suitable or what risk your choice carries.

Two bars: one full-time employee for 40 hours costs Rs 20,000 a week; two part-timers for 15 hours each cost Rs 15,000, saving Rs 5,000 (25%). Induction for two costs Rs 2,400 once, 0.48 of a week of the saving.
Two part-timers cost Rs 5,000 a week less than one full-timer in the bakery example.
Two panels compare internal recruitment (existing staff, one promoted into the vacancy) with external recruitment (a large crowd of outside applicants). Internal is quicker and cheaper, the record is known and it shows promotion is possible, but there are few applicants, no new ideas and the old job must be filled. External gives a larger pool and fresh ideas but costs more, ability is less certain and staff may feel overlooked.
Internal and external recruitment each have benefits and limitations.
Job analysis leads to a job description (the job: tasks, duties, responsibilities) and a person specification (the person: skills, qualifications, qualities), which is used to shortlist; advertising, interviewing and selection follow.
The job description describes the job; the person specification describes the ideal person.

2.3.2 Training

Training is teaching employees the skills and knowledge to do a job well.

Why it matters to a business: higher productivity, fewer mistakes and accidents, better service, use of new equipment, and a flexible workforce. Why it matters to employees: they gain skills, feel more confident, and may earn promotion or higher pay.

Type What it is Benefits Limitations
Induction Introduction for new starters: layout, safety rules, colleagues, duties New staff settle quickly and know the rules; fewer early mistakes Takes time before the person is productive; poor induction can overload a new starter with information
On-the-job Learning by doing the work, beside an experienced colleague Cheap; learning is directly relevant; output continues Trainer’s own work suffers; bad habits can be passed on; the trainee may make costly errors
Off-the-job Learning away from the workstation, such as a college or training centre Specialist trainers; wider skills; no mistakes on live work Expensive; the employee is absent from work; skills may not match this workplace

Worked example. Cordova Textiles must train 8 new machine operators.

  • Off-the-job: course fee Rs 18,000 plus 2 days away at Rs 3,200 a day lost output = 18,000 + 6,400 = Rs 24,400 each; for 8 people, Rs 195,200.
  • On-the-job: a supervisor spends 10 hours per trainee at Rs 600 an hour (Rs 6,000) and extra scrap costs Rs 1,500, so Rs 7,500 each; for 8 people, Rs 60,000.
  • Difference: 195,200 − 60,000 = Rs 135,200.

Cost is not the only test: if mistakes on the machines are dangerous, the dearer course may still be better.

Stacked bars: off-the-job training costs Rs 24,400 per trainee (18,000 fee plus 6,400 lost output); on-the-job costs Rs 7,500 (6,000 supervisor time plus 1,500 scrap). For 8 trainees: Rs 195,200 v Rs 60,000, a difference of Rs 135,200.
Off-the-job training is dearer here, though cost is not the only test.
Induction: a manager welcomes a new starter; helps staff settle in, takes staff time. On-the-job: trainer and trainee work together at the workplace; cheap and real, but mistakes can happen. Off-the-job: staff leave for a training centre; expert teaching, but costly and away from work.
Induction, on-the-job and off-the-job training each have a benefit and a limitation.

2.3.3 Reducing the size of the workforce

Dismissal is when an employer ends a contract because of something connected with the employee, such as repeated serious misconduct or persistent failure to reach the required standard. Redundancy is when the job itself is no longer needed, so the employee loses the post through no fault of their own.

Dismissal Redundancy
Reason The employee’s behaviour or performance The business needs fewer workers
Example Repeatedly ignoring safety rules after warnings A new machine does the work of five people
Replacement Often replaced by a new employee The post is usually removed

When downsizing may be needed: automation replaces tasks done by hand; demand for a product falls; the business closes a branch, loses a major customer, or must cut costs to survive.

Worked example. Ironvale Fabrication has 50 employees paid an average Rs 45,000 a month, a wage bill of 50 × 45,000 = Rs 2,250,000. Demand for one product line has dropped. Removing 8 posts saves 8 × 45,000 = Rs 360,000 a month, which is 360,000 ÷ 2,250,000 = 16% of the wage bill. Any compensation owed under contracts or local law reduces the saving in the first months.

Which employees to make redundant. Base the choice on business needs, not personal dislike: which jobs are no longer needed, whose skills are still required, and who could move or retrain. Always state the downside of your recommendation, such as lost experience or lower morale among those who stay.

Two panels. Dismissal concerns the person: an employee ignores safety rules after warnings and leaves; the post is often refilled. Redundancy concerns the job: a machine does the work of five, the post is crossed out and usually removed, through no fault of the worker.
Dismissal is about the employee; redundancy is about the job.
Fifty employee figures with 8 crossed out. The wage bill is 50 x Rs 45,000 = Rs 2,250,000 a month; removing 8 posts saves Rs 360,000 a month, 16 percent of the bill. Compensation owed reduces the saving at first, and posts should be chosen by business need.
Removing 8 of 50 posts saves 16% of the monthly wage bill.

The syllabus lists five areas. Describe each in general terms.

Area General idea Impact on employers Impact on employees
Employment contracts A written or agreed statement of pay, hours, duties and conditions Must provide clear terms and keep to them; helps avoid disputes Know what is expected and what they will receive
Unfair dismissal Dismissal without a fair reason or fair process is not allowed Must follow a fair procedure; may face penalties if not Protection against being sacked unreasonably
Discrimination Treating people worse because of characteristics such as gender or religion is unlawful in hiring, pay and promotion Must choose and treat staff on ability; may widen the talent pool Fair chance of being hired and promoted
Health and safety A duty to provide safe working conditions Costs of equipment, training and inspection; fewer accidents and absences Safer workplace
Legal minimum wage A lowest hourly or monthly pay set by law Higher wage costs, especially for low-paid labour-intensive businesses Guaranteed minimum income

Worked example. Delmore Coaches pays 12 cleaners Rs 38,000 a month. The legal minimum rises to Rs 40,000.

  • Extra per person: 40,000 − 38,000 = Rs 2,000.
  • Extra a month: 12 × 2,000 = Rs 24,000; a year: Rs 288,000.
  • Rise for each cleaner: 2,000 ÷ 38,000 = 5.3% (to 1 decimal place).

Delmore might raise prices, trim hours or accept lower profit. Employees gain, but the firm may employ fewer people.

Five rows with an icon each: contracts, unfair dismissal, discrimination, health and safety and minimum wage. Each row states in a few words what the employer must do and what the employee gains.
The five legal controls, with what each asks of employers and gives employees.
Bars show monthly pay of Rs 38,000 against a new minimum of Rs 40,000, a rise of Rs 2,000 or 5.3 percent. For 12 cleaners this is Rs 24,000 a month and Rs 288,000 a year. Delmore might raise prices, trim hours or accept lower profit.
A Rs 2,000 rise for each of 12 cleaners costs Delmore Rs 288,000 a year.

2.4.1 Effective communication and methods

Communication is passing information from a sender to a receiver and getting a response. It is effective when the message is received, understood and acted on. Good communication helps decisions, coordination, motivation, safety and customer relations. Internal communication is within the business (managers to staff, staff to staff). External communication is with customers, suppliers, banks and the public.

Method Benefits Limitations
Face-to-face or meeting Instant questions and feedback; shows tone Time-consuming; hard for scattered staff; no record unless minuted
Notice or memo Cheap; reaches everyone passing May go unread; no feedback
Letter or report Formal; permanent record Slow; costly
Email Fast, cheap, attaches files, record kept Can be ignored, overloaded or misread; needs device access
Text or messaging app Immediate, informal, reaches mobiles Short; not suitable for complex or formal messages
Video conferencing Links distant people Needs connection and equipment
Intranet or website Information in one place, always available Costly to keep updated; people must check it
Social media Reaches many customers cheaply Public mistakes spread fast

Worked example. Rosedale Dairy has 90 staff and wants to brief them on a safety change. A 15-minute briefing (0.25 hours) for everyone costs 90 × 0.25 = 22.5 staff-hours, or 22.5 × 450 = Rs 10,125 of working time at Rs 450 an hour. A notice plus email costs little but cannot confirm understanding.

Recommend and justify a method. Decide on four factors: how urgent, how complex, how many receivers, and whether a record or feedback is needed. For the dairy, a short briefing for the change itself, backed by a posted notice and a follow-up email, covers speed, understanding and record.

90 staff figures; a 15-minute briefing is 22.5 staff-hours, Rs 10,125 of working time at Rs 450 an hour. The briefing allows instant questions but leaves no record unless minuted; a notice plus email is cheap and leaves a record but cannot confirm understanding. Together they cover speed, understanding and a record.
Combining a briefing with a notice and email covers speed, understanding and a record.

2.4.2 Communication barriers

A barrier is anything that stops a message being received or understood.

How it arises Problems it causes How it can be reduced
Jargon, or a language the receiver does not share Wrong action taken Plain wording; translation; check understanding
Too many levels in the chain of communication Delay or distortion Fewer levels; direct channels
Overload of messages Important items missed Prioritise; summarise; use fewer channels
Wrong method or poor timing Message ignored Match method to message
Noise, distance or technical failure Message not received Better equipment; written back-up

Problems of ineffective communication include mistakes and rework, delays, lower morale, weaker customer service, lost orders, and conflict between departments.

Internal communication runs both ways between staff and a manager inside the business; external communication runs both ways between the manager and a customer outside. A message travels from sender to receiver, a barrier can block it, and feedback returns. Barriers: unclear wording, different languages, too many levels, equipment fails. Fix: clear words and asking for feedback.
Messages can be blocked by barriers, so senders need feedback.

Common errors

  • Writing “recruit” when you mean “select”, or the reverse.
  • Describing dismissal as cost-cutting. It relates to the employee; redundancy relates to the job.
  • Listing training types without a benefit and a limitation for each.
  • Naming a communication method without saying why it suits this message and these receivers.
  • Treating a calculation as the whole answer. Add a sentence of judgement.

Frequently asked questions

What are the main stages of recruitment and selection? Identify the vacancy, write a job description and person specification, advertise, shortlist applications, interview and test the shortlist and take up references, then offer the post and give induction training.

What is the difference between a job description and a person specification? A job description sets out what the post involves. A person specification sets out the skills and qualities wanted in the person who fills it.

When is communication effective? Communication is effective when the message is received, understood and acted on as intended, with a response from the receiver.

What problems does ineffective communication cause? Mistakes and rework, delays, lower morale, weaker customer service, lost orders and conflict between departments.

How should a business choose which employees to make redundant? Base the choice on business needs rather than personal dislike, such as which jobs are no longer needed and whose skills are still required.
