Introduction

Hundreds of sectors have different corporate sizes and structures. Human resources (HR) is one of the most vital divisions, regardless of how many employees a firm has, ten or thousands. However, for a team to function as effectively as possible, there needs to be a clear structure that enables each member to manage the requirements of the business. An HR organizational structure can assist HR departments in handling that with ease.

The internal structure of the HR department is represented graphically by an HR organizational chart, also known as an HR org map or HR organizational structure. The names of the employees are listed, along with their primary responsibilities, positions, and hierarchical relationships. In departments like human resources, organizational charts are commonly used both within and between departments.

What Is the Structure of an HR Team and Organization?

The HR department and organization are changing from administrative units that oversee the transactional HR tasks of payroll, employee benefits, and record-keeping to teams headed by C-level directors and executives that answer to the C-suite.

In the HR Management Policies & Practices in the United States report, which was created by the Cranfield Network regarding International Human Resource Management in partnership with SHRM, 70% of the organizations that responded stated that HR has a position on the board of directors, and 66% said they have a written HR management plan.

Additionally, responses showed that HR is solely in charge of making important policy decisions. New roles such as CDO (Chief Diversity Officer) and CHRO (Chief Human Resources Officer) have been created as a result of this evolution. The reporting structure of the Vice President of Human Resources and CHRO has changed.

To whom is human resources accountable?

As a result of these changes, HR departments today have a more strategic role within an organization, and HR managers and directors are communicating with the company’s CEO, CFO, and COO. The size and makeup of HR departments are influenced by how big your company is, the industry you are in, the pace of change within that industry, and how much HR responsibility is outsourced or brought in-house.

Fundamentally, having people (or teams) that are each experts in important human resource tasks is the best method to set up the HR Organizational Structure, irrespective of the scale of your company. For example, a team or individual may concentrate on learning and growth, another on financial matters (pay, benefits, & so on), and a third on compliance and labor and employee relations.

The online gaming industry, where casinos also profit from specialist teams managing different operational areas, is a good example of this specialized approach. The teams that make up your HR department’s design will ultimately depend on your business’s demands.

Beginning with the head of the Human Resources department, we should define the function and the person to whom it reports. These roles vary greatly, usually depending on the size of the firm or the ratio of tasks that are externally sourced vs those that are internally sourced. If they want to submit a yearly LLC report, for instance, an HR team member must first speak with their CEO (internal) before sending it to the external Secretary of State.

The CEO and HR can probably speak directly if the limited liability company is small. In a larger company, though, they will have to first talk to their deputy or another squad member. Annual reports give useful details. The HR leader reports to the CEO as a respected member of the management team, even though they frequently aren’t on the management team or regarded as peers by the business board. In certain organizations, this is when the HR Business Partner’s (HRBP) supporting function enters the picture.

The organization’s missions and goals are the focus of the resources provided by HR business partners, who also have customers within the company. Compliance & administration are given far less attention, and an employer using HRBPs usually has a central HR department or shared services team to manage benefits, compensation, and policy formulation and enforcement.

This kind of HR Organizational Structure is found in large corporations. That being said, a small one can also profit from it. Services related to human resources could be contracted to specialized companies that offer comprehensive solutions for small & medium enterprises.

Organizational Structure: What Is It?

For the purpose of specifying how employees fit into an organization, creating org charts, and arranging personnel, businesses utilize organizational structures. The size of the Human Resources department and other variables will determine the organizational structure that best meets your demands and reflects the broader company. First, I wanted to discuss the common sorts of organizational structures before we get into the particular HR organizational reporting structures.

Types of Common Organizational Structures

Though there are countless organizational structure types available to companies, there are a few choices that contemporary corporations consistently adopt. The following three types of organizational structures are the most prevalent:

Functional Structure

The most prevalent type of organizational structure is a functional organizational structure. In light of this, the following three HR department team arrangements are examples of those found in organizations. Human resource information systems (H.R.I.S.), payroll, benefits, salary, employee relations, design of organizations, development and training, and recruiting and staffing are all part of the HR Organizational Structure.

Flat Structure

In contrast to functional structures of organization, flat organizational structures may feature few or no middle management personnel. Employees and supervisors operate on an even playing field since it is actually flat, meaning there are fewer managerial levels.

A VP of HR can have as many as seven direct reports, and that could be anywhere from recruiting, benefits, payroll, HR business partners, training and development, etc. None of those folks are people managers in their own right – they’re all the same level, and they report straight to the vice president of HR.

By dividing duties and authority evenly throughout the HR department, this model gets rid of workplace disputes and red tape and allows everyone to participate in decision-making. In startups and small businesses, this is typical.

Matrix Structure

A matrix organizational design is a business structure where the reporting lines are arranged as a matrix, or grid, as opposed to the conventional hierarchy. This structure allows for greater flexibility & collaboration, which makes it ideal for project management. In HR, various teams collaborate with one another. Instead of managing a single team, a functional manager receives reports from staff members in many departments. In HR, field HR leaders who are a part of the project team typically use this kind of structure. In the retail industry, the Central Region’s HR Director leads a small staff of recruiters, HRBPs, and trainers to assist that region.

Other Types of Less Commonly Used Organizational Structures

Although the aforementioned organizational structures are the most widely used, you can utilize different ones to develop your company’s organizational structure or HR staff. A few more uncommon choices are as follows:

Organizational Structure by Division. Large businesses that have a divided organizational structure should use this.
Network-based organizational Structure. Two or more separate organizations working together in some manner for business objectives is known as a network organizational structure.
Team-based organizational Structure. A team, or unit-based, organizational structure is the type of company model that works when teams of workers work together to achieve a common objective under the supervision of a single supervisor. The section that follows provides some examples of organizational reporting structures for HR.

Ideal number of employees for your HR department

The size of the company, commitment to its values and people, geography, and leadership are the main drivers of HR Organizational Structure. The HR to staff ratio can serve as a benchmark for companies to determine whether the department needs further HR support. The HR personnel ratio is simply the number of workers divided by the number of HR team members.

For every one hundred workers that the HR department serves, the median human resources to staff ratio was 1.4 in 2017, according to Bloomberg BNA. The ACA’s modifications, the growing need for talent, and the overtime regulations have all contributed to this ratio’s considerable increase.

How to Calculate the HR to Employee Ratio

When it involves your HR team, how do you think about the employee ratio? The comprehension of the more strategic function that HR plays in helping the greater organization depends on HR measures such as these.

The HR to Employee Ratio is calculated as follows: Employees / HR Team Members. Since HR departments have drastically decreased in number during the economic downturn, this ratio is significant. Employees at call centers provide external customer service, while HR provides internal customer assistance.

NOTE: Revenue is also considered when categorizing companies as small, medium, or large, but our focus here is on employee number. There is a general rule of thumb. Small businesses have less than 100 employees, mid-sized companies range from 100 to 999 employees, & large organizations have 1,000+ employees.
