Can I get dismissed?
If you are employed by a Dutch company, you can basically only be dismissed if your employer has a valid reason to do so. For example, if you perform poorly or misbehave despite several warnings. Dutch labor law prescribes which grounds for dismissal are permitted. You'll find the most common reasons here.
There are exceptions though. Dismissal by mutual consent is one of them. If you and your employer mutually agree to end your employment contract, you can do so by drafting a settlement agreement. In some occasions your employer might offer you a settlement agreement, even though there is no valid dismissal reason. If that happens, you are in a strong negotiating position.
In some cases you can't be laid off at all. That might occur if you're ill or pregnant. In others, there is no reason required to fire you. For instance if you have reached retirement age or if you're still in your trial period.
