If the undeclared market is socially accepted or the existence of the formal system is not sufficiently known in the population, it would be wise to consider implementing measures that are designed to increase the attractiveness of the formal PHS sector (besides quality and price). Two types of measures are particularly pertinent:

• Communication campaigns to raise awareness on the illegality and dangers of undeclared work. Responsibilities and duties of PHS employers should also be stressed, to make sure that they understand what they may encounter or risk while they continue to depend on undeclared work.

• Communication campaigns to promote the formal system.
