Mothers of families who have retired since September 1st are supposed to benefit from a more favorable pension calculation, which takes into account the 23 or 24 best years of their careers. This change was intended to provide a fairer pension for those who may have taken time off work to care for children, allowing them to use their highest-earning years to determine their retirement income. However, according to the Retirement Insurance, this benefit is not currently being applied, as reported by the newspaper Ouest-France. The issue stems from a technical problem with the system used to calculate pensions. The new rules were implemented to ensure that people who took career breaks to raise children are not unfairly penalized when calculating their retirement benefits. However, due to an error in the system, these adjustments are not being properly applied to the affected retirees. This has left many retirees confused and concerned about the accuracy of their pensions. Some have reported receiving letters from the Retirement Insurance indicating that their pensions were calculated using the old rules, even though they should be eligible for the new, more favorable method. As a result, some individuals may be receiving less than they are entitled to. The Retirement Insurance has acknowledged the issue and is working to correct the errors. However, it is unclear how long it will take to resolve the problem and ensure that all affected retirees receive the correct pension amounts. In the meantime, those affected are advised to contact the Retirement Insurance directly for clarification and assistance.
