Two kinds
An internal second job — at the main workplace. An external second job — with another employer.
How it is set up
Under article 435 of the Labour Code, the parties sign a separate employment contract, and the employer issues an order. The contract must state that the work is a second job.
Limits
Under article 433 of the Labour Code, a second job is not allowed: for persons under eighteen years of age; on work with unfavourable conditions, if the main work has the same conditions (health system workers are an exception); in the other cases that the legislation gives.
Leave
A second job also carries leave. Under article 439 of the Labour Code, it is given at the same time as the annual leave at the main workplace.
