What is an employee reference?
A reference is a formal opinion about an employee issued by their previous employer, supervisor or colleague. This document plays a key role in the recruitment process, because it provides the future employer with information about how the employee performed in previous workplaces, what position they held, and what skills and competences they have.
It is worth noting that references differ from a general opinion about an employee. Opinions are usually a more general assessment of the employee as a person, often without detailed reference to their work results or specific tasks. Professional references, on the other hand, should contain precise information about the employee's duties, the position they held, and their most important achievements.
A reference letter is a document that becomes part of a job application, just like a CV or a cover letter. That is why it is important for it to be written in a professional and clear manner, so that the future employer can easily understand what a given candidate can bring to the company.
Who can issue a reference for an employee?
References for an employee can be issued by people who had direct contact with their work and are able to assess their competences and achievements:
- Direct supervisor – References are most often issued by the direct supervisor, who knows the employee's work, tasks, achievements and competences best. As the person responsible for supervising the employee, they can assess their skills most objectively. A letter of recommendation from a supervisor, especially at the end of the employment relationship, is often a key document in the recruitment process. References in a CV can therefore contain valuable information about the employee's characteristics, which may prove important to the future employer.
- HR department – In some cases, especially in larger companies, references may be issued by the HR department. Such references are usually more formal, but still contain key information about the period of employment, the position held and an overall assessment of the employee. References for a CV issued by HR are also an important document, confirming that the employee was employed by the company during a specific period and met the requirements of the position. The HR department can also prepare references that take into account the employee's experience and skills, and the references should include information about their contribution to the company's development.
- Colleagues – Sometimes references can be issued by people the employee worked with directly. Such an opinion can be a valuable complement to formal references, because it often provides additional information about day-to-day cooperation and relationships within the team. A reference letter for an employee from a colleague can include details about their teamwork and interpersonal skills, which may prove invaluable to a new employer. A letter of recommendation can be written both by workmates and by mentors who knew the employee's contribution to team activities well.

How to write a reference for an employee?
When writing a reference for an employee, it is worth keeping in mind several key elements that should be included in the document. A well-written reference letter should be not only detailed, but also concise and clear. Here are a few tips on how to create an effective reference letter.
Structure of a reference
- Header – At the beginning of the document, include the details of the person issuing the reference (name and surname, position, company name) and contact details, so that the new employer or recruiter can get in touch if needed. It is also worth including the date the reference was issued.
- Introduction – In this section, briefly describe what position the employee held in the company, how long they were employed, and to what extent you worked with them on a daily basis. The introduction should be clear and informative, so that the reader immediately knows who the employee was.
- Description of duties and achievements – This is the key part of the reference, in which you should include details of the employee's main tasks, their achievements, and the skills they used at work. You can also highlight specific successes that had a positive impact on the company.
- Assessment of the employee's competences and qualities – Focus on the soft and hard skills that distinguished the employee, such as the ability to work in a team, time management, communication skills, or specialist knowledge. It is also worth emphasising the character traits that were important in day-to-day work.
- Closing – At the end of the document, it is worth including a general recommendation, stating whether you recommend the employee for a new position and what professional prospects you see for them. It is also worth encouraging the reader to get in touch with any questions.
- Signature and contact details – Every reference letter should be signed by the person issuing the reference and include their contact details, so that the new employer can confirm the authenticity of the document.
Practical tips
- Be objective – References should be based on facts and specifics. Try to avoid generalities that do not give the new employer a full picture of the employee.
- Keep a positive tone – Even if working with the employee was not always ideal, it is worth focusing on the positive aspects of their work. Negative comments may discourage a potential employer.
- Tailor the reference to the position – If you know what position the employee is applying for, try to highlight the skills and qualities that will be particularly useful in the new role.
- Avoid overly long references – The ideal reference letter should fit on one page. Descriptions that are too long may be skipped by the recruiter.
Can an employer refuse to issue a reference?
An employer is not obliged to issue a reference for an employee. It is a form of courtesy, dependent on the company's internal policies and the individual decisions of the people responsible. In the case of employees who had difficulty performing their duties, the employer may refuse to issue a positive reference or prepare a more neutral opinion.
References can also form part of a letter of recommendation, which builds a positive image of both the company and the employee on the labour market. Good references should present the specific employee in a positive light, drawing attention to their strengths and contribution to the company's development. If references for a CV contain this information, they can significantly increase the candidate's chances in the recruitment process.
In the case of employees in more junior positions or interns, references may be more general in nature. An opinion about an intern often contains information about their knowledge and the progress they made during the internship. Such references can be a valuable addition to a cover letter, especially for young people who are just starting their career on the labour market.
Writing both a letter of recommendation and a reference letter requires diligence and presenting facts that will matter to the future employer. It is worth including in the references the employee's most important qualities and information that will be helpful to a potential recruiter.
What mistakes should you avoid when writing a reference for a former employee?
Preparing references requires prudence and responsibility. Here are the most common mistakes worth avoiding:
- Information that is too general – Avoid generalities such as "a good employee". Instead, give specific examples of successes and skills that best convey the employee's value.
- A negative tone – References should be kept in a positive tone. A negative opinion can harm a former employee, even if they encountered difficulties in their previous job.
- Missing contact details – A new employer may want to verify the reference during recruitment, so remember to provide your phone number or e-mail address.
- Missing signature – A reference letter without the signature of the person issuing the reference is not a credible document. Every reference should bear the signature of the person issuing it.
Summary
An employee reference is a document that can play a key role in the recruitment process. A reference letter should be objective, concise and kept in a positive tone, containing information about the position, duties, achievements and an assessment of the employee's competences. An important element is also including the employee's contribution to the team's work and their specialist knowledge, which can be a valuable pointer for the future employer.
Although an employer is not obliged to issue references, at the employee's request they often decide to provide such a written document. It is worth ensuring that the reference letter is not limited only to formal information about the duties performed, but also contains a more subjective assessment of the employee, highlighting their strengths and successes. Well-written references can significantly support an employee's career, presenting their competences in a positive light and giving potential recruiters a solid basis for assessment.
By following these tips, you can create references that will be real support for a former employee and contribute to their further professional success.
