I'm currently working as a software developer for a small company (9 persons) in France. For different reasons, mostly because I feel at a dead end in this job and I don't see any ways how this could change, I have decided to resign. I will give my resignation in the following days and I have a 3 months notice.
In June, there is an exhibition where all the major players of the industry present their new stuff. My company has planned to present the version 2 (v2) of the product I'm working on (I'm the only developer working on it). The v2 is still in development.
If I resign now, I'll stop working in mid May because of my 3 months notice - one month before the v2 needs to be presented in the exhibition. Even if the company manages to hire a new developer to replace me before the exhibition, it is highly unlikely that the v2 will be ready in June. This will put the company in a bad position for the exhibition.
So my question is : can my resignation be considered as abusive?
I'm getting along well with everyone, have nothing against my colleagues, and I just want to leave because the job has lost interest. I have no intent to burn bridges or harm my employer.
In France "démission abusive" exists ("abusive resignation", or "unfair resignation", I'm not sure. I'm not even sure it exists outside of France). It can happen when an employee resigns with the intent to harm its employer (such as an accountant resigning the day of the accounting balance sheet). I have never seen it used anywhere, but I'd like to make sure I can't be accused of that. The law in question is article L1237-2 of Code du travail ("work law"), which however does not define what exactly is considered "abusive" resignation.
Update : All the answers and comments agree that it's not abusive resignation, so I'll keep my plans to find better opportunities and resign. I probably was overthinking. Thanks for the help!
