The role of human resources in a business

Human resources involves managing a firm's employees to ensure they work effectively. It focuses on the people who contribute to running the business, whether through a dedicated department or handled by management in smaller firms.

The human resources function ensures that all employees have the necessary skills and abilities to perform their roles. It also identifies and meets the broader workforce needs as the business evolves.

Key activities of human resources

• Recruitment and selection - Identifying areas where additional staff are required and hiring suitable candidates to fill those roles.
• Training and development - Organising programmes to improve employees' skills and abilities, helping them perform better in their jobs.
• Motivation and dispute resolution - Supporting staff to feel motivated at work and resolving any conflicts or issues that arise among employees.
• Workforce planning - Assessing future staffing needs as the business grows or changes, including decisions on hiring or redundancies.

Key roles within organisational structures

Organisational structures outline how employees are arranged within a business, making it clear who is responsible for specific tasks. This clarity ensures all activities are covered and helps the firm operate smoothly. Most structures include layers, with four main roles carrying different levels of responsibility.

The four basic roles in an organisational structure

1. Directors - Sit at the top level and set the overall strategy and targets for the business, often decided during board meetings.
2. Senior managers - Implement the directors' strategy by organising teams; they may oversee middle or junior managers.
3. Supervisors or team leaders - Rank below managers and handle day-to-day oversight of specific projects or small groups of workers.
4. Operatives - Perform assigned tasks without managing others; they form the base level of the structure.

Concepts of hierarchy in organisations

Hierarchies create a layered system where authority flows from top to bottom. Directors occupy the highest layer, while operatives are at the lowest. This setup establishes clear lines of responsibility and communication.

Key hierarchy concepts

• Chain of command - The pathway linking directors to operatives, through which instructions and information pass.
• Authority and subordinates - Individuals at higher levels have power over those below them, who are known as subordinates.
• Delegation - The process of passing responsibility down the hierarchy to lower levels.
• Span of control - The number of subordinates directly reporting to a single manager.

Tall and flat organisational structures

Businesses can adopt different structures, which affect management styles, communication, and efficiency. The choice influences how closely employees are supervised and how quickly decisions are made.

Tall organisational structures

Tall structures, also known as hierarchical, have many layers and a long chain of command.

Features of tall structures:

• Narrow span of control - Managers oversee a small number of subordinates, allowing closer monitoring.
• Communication challenges - Messages take longer to travel through multiple layers, often requiring formal meetings; electronic tools can help speed this up.

Flat organisational structures

Flat structures have fewer layers and a short chain of command.

Features of flat structures:

• Wide span of control - Managers handle a large number of subordinates, which can make oversight more difficult.
• Communication advantages - Shorter chains enable faster messaging; group methods like team meetings or bulk emails work well for consistent information sharing.

Factors influencing the choice of organisational structure

The most suitable structure depends on various business factors, such as size and growth. Effective structures balance the span of control with the chain of command to support efficient operations and communication.

Influences on organisational structure decisions

• Business size - Small firms often use flat structures, typically managed directly by the owner; larger firms add layers as they grow, increasing management costs.
• Growth and delayering - Expanding businesses may introduce more managers to handle complexity, but excessive layers can be removed through delayering to reduce hierarchy.
• Working arrangements - Factors like the use of temporary or part-time staff can reduce the need for multiple management layers, allowing for flatter structures.
