If the Institute for Employee Benefit Schemes (UWV) considers you partially unfit for work, you do not need to report your situation to us. NN CDC Pensioenfonds will receive this information from the UWV . They will also report a change in your percentage of incapacitation.
In principle, you will stay employed by NN/NN IP. Your pension accrual will be continued as usual, but you will only be required to pay your own share of the pension contribution for the hours that you are working. If your employment is terminated after all, your pension accrual for the hours that you were working will be discontinued. However, your pension will continue to accrue for the hours that you were on sick leave before your employment was terminated.
If you wish, you can take out insurance at Nationale-Nederlanden to cover the WGA gap (Resumption of Work by Partially Fit Persons Regulation). You can do this via Workday. The HR startpage of NN/NN IP offers you more information.
