Personnel management: looking after people
A factory is not only machines. Personnel management (also called human resource management) is the work of choosing, training, paying and caring for the people who work there.
- Hiring: find the right person for each job.
- Training: teach the work and the safety rules.
- Pay and rewards: wages on time, fair to everyone.
- Safety and welfare: clean drinking water, rest breaks, safe machines.
- Teamwork and records: attendance, leave and a way to listen to problems.
Happy, trained workers make fewer mistakes and fewer accidents.
Industrial accounting: keeping the money records
Accounting means writing down every coin that comes in and goes out. In a factory we also find the cost of making one item.
- Fixed cost: does not change with the number made (rent, manager salary).
- Variable cost: grows with each item (material, power).
- Total cost = fixed cost + variable cost.
- Profit = income from sales - total cost. If it is negative, it is a loss.
- Break-even: the number of items where profit is exactly zero.
Break-even items = fixed cost / (selling price - variable cost per item).
Laws on factory management
Every country has laws so that factories treat workers and neighbours fairly. The names differ, but the ideas are the same everywhere:
- Wages: a minimum wage and pay on time.
- Working hours: a limit per day and week, with rest days and extra pay for overtime.
- Safety and health: guarded machines, fire exits, protective gear.
- Registration and licences: the factory must be registered and inspected.
- Fair treatment: no child labour, no unfair dismissal.
- Environment: limits on smoke and waste water.
Breaking these rules can lead to fines or closure.
Industry and entrepreneurship
An entrepreneur is a person who starts a new business and takes the risk. The path is simple:
- Idea: solve a real need (a better, cheaper or new product).
- Plan: who will buy, what it costs, how much to charge.
- Money: own savings, a loan or investors.
- Start small: test, learn, then grow.
Good entrepreneurs are curious, patient and honest with their numbers. Their factories create jobs and useful goods.
Try it: pick a snack you could make at home. Write the cost of material for one packet, a price you would charge, and how many packets you must sell to cover a fixed cost of rent.
Key formulas and definitions
- Total cost = fixed cost + (variable cost per item x items)
- Income = selling price x items sold
- Profit = income - total cost
- Break-even items = fixed cost / (price - variable cost per item)
Worked examples
1. A unit sells an item for 20 coins. Material and power cost 12 coins per item. Fixed cost is 400 coins a day. Find the break-even number of items.
Each item gives 20 - 12 = 8 coins towards fixed cost. 400 / 8 = 50 items.
2. Using the same unit, find the profit when 80 items are made and sold.
Income = 80 x 20 = 1600. Cost = 400 + 80 x 12 = 1360. Profit = 1600 - 1360 = 240 coins.
3. A law allows 48 working hours a week. A worker works 9 hours on each of 6 days. Was the limit crossed?
9 x 6 = 54 hours, which is more than 48. Yes, by 6 hours, so overtime rules and extra pay apply.
Common mistakes
- Counting income as profit. Profit is what is left after ALL costs.
- Forgetting the fixed cost when finding total cost.
- Thinking safety training is a waste of time. One accident costs far more than training.
- Believing laws are only for big factories. Small units must follow them too.
