In the private sector, an internal promotion allows an employee to move into a more highly skilled role or one involving greater responsibility without changing companies.
It may also lead to changes in salary, employment status or job classification. Before accepting a promotion, employees should make sure they fully understand the proposed conditions.
What is an internal promotion?
An internal promotion involves moving to a higher-level position within the same company.
The change of position may be hierarchical, for example when a warehouse operative becomes a team leader. It may also be based on expertise, such as when an employee becomes a technical specialist without managing other employees.
A promotion is therefore about more than a new job title. The employee’s duties should evolve and involve a higher level of expertise, autonomy or responsibility.
It should not be confused with a pay rise either. An employee may receive a pay rise while remaining in the same position. Conversely, there is no general rule requiring employers in the private sector to increase an employee’s salary with every promotion. However, the applicable collective bargaining agreement and the new job classification may establish a minimum salary that must be respected.
What is the difference between promotion and internal mobility?
Promotion is a form of internal mobility, but not every internal move is a promotion.
An employee who becomes responsible for their team moves up the hierarchy and therefore receives a promotion. If they join another department with a comparable level of responsibility, they change positions without moving up in rank. This is known as horizontal mobility.
The difference therefore lies in the nature of the change. Internal mobility covers any change of position within the same company. A promotion involves progression in terms of qualifications, responsibilities or seniority.
How is an internal promotion decided?
A company may offer a position directly to an employee or open it to internal applications. Its decision should not be based solely on seniority or on the employee’s performance in their current role.
The skills required for the new position may be very different. An employee who has mastered their profession does not automatically have the skills needed to organise a team’s work, train colleagues or make decisions.
Motivation also matters. Some employees want to deepen their expertise without becoming managers. A promotion should therefore align with their career development, rather than simply meeting the company’s needs.
Selection criteria must be relevant to the position and applied consistently to all candidates. Age, sex, health, family circumstances or any other prohibited criterion cannot justify denying someone a promotion. Such a decision may constitute workplace discrimination.
What should employees check before accepting a promotion?
A job title alone is not enough to assess a proposal. Employees should first understand the duties they will actually perform and the results the company expects from them.
The entire compensation package should be reviewed, including basic salary, bonuses, benefits and any variable pay. Working hours, workplace location, employment status and working-time arrangements may also change.
Before making a decision, employees should receive information about:
- the job title and responsibilities;
- the start date;
- the proposed salary and bonuses;
- the applicable job classification;
- the working hours or working-time arrangements;
- any probationary period for the new role;
- the training or support provided.
These details make it possible to understand what the promotion will actually change beyond the new job title.
Does an internal promotion automatically result in a pay rise?
A promotion does not automatically result in a pay rise in the private sector. No minimum percentage applies to all companies.
However, the salary must comply with the minimum levels established by law and the applicable collective bargaining agreement. If the new position falls within a higher job classification, the employer must pay at least the corresponding collectively agreed minimum salary.
A pay rise may also be negotiated to reflect the additional responsibilities. Negotiations can cover basic salary, bonuses, targets linked to variable pay and other benefits.
It is advisable to obtain a detailed financial offer before accepting the promotion. A promise of a future salary review is no substitute for a clearly defined amount and implementation date.
Is an amendment to the employment contract required?
An amendment to the employment contract can be used to formalise the conditions of the promotion. It may specify the new position, salary, professional classification, working hours and start date.
The employee’s agreement is required when the proposal affects an essential term of the employment contract. In particular, an employer cannot impose a change in salary or professional classification.
However, not every change in duties constitutes a change to the employment contract. When the new duties remain consistent with the employee’s professional classification, they may simply amount to a change in working conditions. The answer therefore depends on the original contract and the extent of the proposed changes.
Employees should be given enough time to read the amendment before signing it and verify that its contents match the conditions discussed.
Can a probationary period be introduced for the new position?
A probationary period for the new role may be introduced to determine whether the employee can adapt to the position. It also gives the employee time to decide whether the new responsibilities suit them.
This arrangement should not be confused with the probationary period that may apply when starting a new employment contract. The existing employment contract remains in force. If the internal probationary period is ended, the employee returns to their previous position.
The applicable collective bargaining agreement may authorise or prohibit this arrangement. Its duration, possible renewal and termination conditions must be defined in advance. When introduced, the probationary period for the new role must be included in an amendment to the employment contract.
Can an employee refuse a promotion?
An employee may refuse a promotion when it changes an essential term of their employment contract. An employer cannot impose a change in salary or professional classification, for example.
The employee may refuse because the new working hours are less suitable, the position involves additional travel, the proposed salary is insufficient or they do not wish to take on the additional responsibilities.
The situation is different when the new duties remain consistent with the employee’s professional classification and do not alter the employment contract. They may then be treated as a change in working conditions. The proposal must therefore be examined carefully to determine whether the employee’s consent is required.
What are the benefits of an internal promotion?
For employees, a promotion provides an opportunity to progress in a familiar working environment. They can develop their skills, take on greater responsibility and negotiate new compensation arrangements.
The employer, meanwhile, already has concrete information about the selected employee’s work and professional background. The employee may adapt to the company more quickly, although they will still need time and support to settle into the new role.
Internal promotion also demonstrates that career development opportunities exist within the company. To remain credible, the process must be based on clear and understandable criteria. An opaque decision or one based on personal preferences is more likely to create a sense of unfairness.
How should the transition into the new role be prepared?
The transition into the new role should be carefully prepared, even when the employee already knows the company well. They may need professional training, particularly if they are becoming a manager for the first time or must learn to use new tools.
A handover with the previous job holder can make the transition easier. When this is not possible, progressive objectives can prevent the company from expecting the employee to master the role immediately.
Regular discussions with the manager can then help review priorities, identify difficulties and assess training needs. Support should be planned from the outset rather than introduced only after problems arise.
