Nature of contract and performed work
In theory, the employee can decide what contract he will sign. In reality – a lot depends on the employer and the practise of a given company. It should also be remembered that the type of contract to be executed depends primarily on the type of work to be performed. At the moment there are 3 most popular types of contracts: a contract of employment, a mandate contract, and a contract for specific work. More on that topic in the article: Employees’ rights.
