In case of illness, dismissal can be done either through a settlement agreement (VSO) or through the UWV, but the best depends on your situation. A VSO is often quicker and gives room to negotiate additional compensation and conditions, such as payment of holidays or a favourable end date. Dismissal through the UWV usually takes longer and offers less room for negotiation, but is tested against the legal conditions, which can give extra legal certainty. In many cases, a VSO provides more flexibility and financial benefit, provided it is properly checked legally.
