2.5 Employment Contracts – Benefits & Legal Controls (AO1‑AO4)
Why a contract?
An employment contract is a legally binding agreement that sets out the rights and responsibilities of the employer and the employee. It provides a clear framework for the employment relationship and protects both parties.
Benefits for Employers (AO2)
- Clarity of expectations – duties, hours, performance standards and remuneration are defined.
- Legal protection – reduces risk of disputes, unfair‑dismissal claims and breach of contract actions.
- Cost control – specifies salary, overtime rates, bonuses and any other financial commitments.
- Performance management – includes appraisal, training and disciplinary procedures.
- Business continuity – notice‑period clauses and succession‑planning help minimise disruption when staff leave.
Benefits for Employees (AO2)
- Job security – terms of employment and conditions for termination are set out.
- Clear remuneration – salary, overtime, bonuses and benefits are recorded in writing.
- Statutory rights – holiday entitlement, sick pay, maternity/paternity leave and other legal rights are confirmed.
- Career development – training, promotion pathways and performance‑review procedures are often included.
- Dispute resolution – a fair process for handling disagreements is usually outlined.
Comparison of Benefits
| Benefit | Employer Perspective | Employee Perspective |
| Clarity of terms | Defines duties, hours and pay, reducing ambiguity. | Provides a clear understanding of what is expected and what is received. |
| Legal protection | Limits exposure to unfair‑dismissal claims. | Ensures statutory rights are respected and enforceable. |

- Helps a business to achieve its objectives (e.g., increase market share, profit).
3.2 Market Changes & Segmentation (AO2‑AO3)

4 Operations Management
4.1 Production Methods (AO1‑AO2)
- Job production – one‑off items (custom furniture).
- Batch production – groups of items (baked goods).
- Flow (mass) production – continuous, high volume (car assembly).
- Lean production – minimising waste, just‑in‑time inventory.
4.2 Costs & Economies of Scale (AO2‑AO4)
- Fixed costs (rent, salaries) vs. variable costs (materials, energy).
- Economies of scale – average cost falls as output rises (spreading fixed costs).
- Diseconomies of scale – inefficiencies when a firm becomes too large.
4.3 Break‑Even Analysis (AO2‑AO3)
Break‑Even Point (BEP) = Fixed Costs ÷ (Selling Price per unit – Variable Cost per unit)
| Item | Amount (£) |
| Fixed Costs | 30,000 |
| Selling price per unit | 25 |
| Variable cost per unit | 15 |
| BEP (units) | 3,000 |
Interpretation: The business must sell 3,000 units to cover all costs; any sales beyond this generate profit.

| Feb | 55,000 | 48,000 | 7,000 |
| Mar | 60,000 | 52,000 | 8,000 |
Positive net cash each month indicates good liquidity.
5.3 Income Statement (Profit & Loss Account) (AO1‑AO2)

| Operating Expenses | 30,000 |
| Operating Profit | 50,000 |
| Interest | 5,000 |
| Profit Before Tax | 45,000 |
| Tax (20 %) | 9,000 |
| Net Profit | 36,000 |

| | Owner’s equity | 130,000 |
| Total | 230,000 | Total | 230,000 |
5.5 Ratio Analysis (AO2‑AO4)
- Gross profit margin = Gross Profit ÷ Sales × 100 = 80,000 ÷ 200,000 × 100 = 40 %.
- Current ratio = Current Assets ÷ Current Liabilities = 80,000 ÷ 30,000 ≈ 2.7 (healthy liquidity).
- Interpret results and suggest actions (e.g., improve inventory turnover if current ratio is too high).
Key Terms: cash flow forecast, income statement, balance sheet, gross profit margin, current ratio, retained earnings.
6 External Influences on Business
6.1 Economic Cycle (AO1‑AO2)
- Phases – expansion, peak, recession, trough.
