In NL I guess that is similar to France; in our case we always started a binder on a new employee so after their trial period/temp contract, we continue collecting info. If that person just waited for the trial to be over to just do nothing, we go to the court with the binder and get them out. We stopped after a certain period depending on what we collected so far: most binders are empty anyway. Also, you can fire someone without that if you have economic cause (which should be the reason for firing someone good) or you can fire them without that by paying them some months in the future.
The most annoying people, which we didnt have many but still a few, are the ones who, right after the trial period, or when they smell a rat, will go 'oh no, i feel something behind my eye and in my wrist, your work made me ill' and then go home. you would have to pay them and be nice about it (not threaten them with a beating).
