On Thursday 18 June 2026, Luxembourg trade union ALEBA released a statement regarding the indexation of the loyalty bonus provided for under the Banking Collective Agreement (CCT Banques).
According to ALEBA, the loyalty bonus is calculated based on an employee's length of service and corresponds to a percentage of their basic salary. The collective agreement explicitly provides that the bonus is paid together with the salary for the month of June.
The trade union argued that the basic salary applicable at the time of payment should serve as the basis for calculating the bonus, namely the June salary. As basic salaries increased by 2.5% from 1 June 2026 following indexation, ALEBA stated that the loyalty bonus should also benefit from this increase.
The reference period running from 1 June 2025 to 31 May 2026 is intended solely to determine the applicable pro rata amount based on an employee's working time during that period. This reference period is used to calculate the attendance rate or employment rate to be taken into account for payment of the bonus and not to determine the salary basis for the calculation.
However, ALEBA claimed that the Luxembourg Bankers' Association (ABBL) had recommended that its members use the May 2026 salary as the reference salary for calculating the loyalty bonus.
The trade union described this interpretation as unfavourable to employees in the sector and said it was not acceptable.
As provided for under the Banking Collective Agreement, ALEBA said it would refer the matter to the Joint Committee established between the signatories of the collective agreement in order to clarify the situation and defend the interests of employees in the banking sector.
