How adequate is it to use "working code" in your own projects?

Question

Law in IT

Hello everyone
1) You work as a Java developer on a project that builds a logistics system.
2) You are doing your project in the field of e-commerce (let's say an online store).
You understand that some of the common modules (authorization, payment gateway, geo-module, etc.) that you wrote for work are suitable for your project.
1) Can I reuse my own working code in my own project?
2) If you work in Java and you write your project in Java, can your employer sue you, arguing that you most likely stole code from work? (although in fact this is not the case). Those. do you need to use a different stack for your project to ensure you don't steal anything from work?

Answer 1

1. You can't. This is theft.
2. Any stack can be used. If you want fewer questions and have a trump card "Yes, I use other technologies here," then it's a good move. They recently discussed
on VC.ru , an employee used his development in the company, and when he quit he almost lost his rights to it. and here is a quote from another article : """ An employee work is a work created by an employee as part of his job duties. It can be a program code, advertising slogans, graphic solutions for an Internet site. Naturally, the employer is sure that since the employee created such an object , then the rights to use it belong to the company.This is also evidenced by Article 1295 of the Civil Code of the Russian Federation.
"""

Answer 2

there is no "your own working code"
there is an intellectual property object that arose as a result of your work and belongs to the employer or there is no such object.
further, I think everything is clear.
