Undeclared work is any work provided by a private individual for and under the authority of an employer, but without signing an individual work contract. The practice of employing persons based on verbal agreements is more often used in relation to males, mainly in such areas as agriculture, trade and the building sector, IPN reports, quoting the National Bureau of Statistics.

Some 7.1% of the salary earners got pays illegally (8.8% of men and 5.7% of women). These worked primarily in agriculture, trade and the building sector.

Some 15.9% of all the economy employees in 2018 worked in the informal sector, as opposed to 14.9% in 2017. The informal sector employees include all the persons who, regardless of their professional status, work for unregistered enterprises, without a legal status.
