The burden of the proof is thus reversed from the general rule and an attitude purely passive on the part of the individual in this respect is sufficient to entitle him to public succour. On the other hand, it is not sufficient for the discharge of all such obligations on the part of the State if it merely offers the individual any employment whatsoever. For it does not serve the community in any way, as the most interested party, when an individual is employed in work for which he is not fitted. The community, therefore, must procure work corresponding to the mental and physical powers of the individual and to his capacity. If the State does not succeed in doing so, it is obliged to furnish him a livelihood. * * * * * To put into operation the principles thus enunciated by the Constitution, different laws are necessary--a law on the offer of employment, a law protecting labour, a law on the help to be given to the unemployed. Such laws have not yet been enacted. However, a certain number of ordinances have been passed that constitute on the part of the Reich the beginning of the execution of the new obligations imposed upon it. First, measures have been taken to procure employment for individuals. To this end, aside from the ordinance of December 9, 1918, which imposes on municipalities the obligation of organizing employment bureaus, public and impartial, there is also an ordinance of May 5, 1920,[52] creating for the Reich a bureau devoted to finding employment. This agency has for its principal function a survey of the labour market and the editing of periodical bulletins on the situation in this market for the purpose of establishing an equilibrium between supply and demand in the different regions and in the different vocations. Measures have been taken also to protect labour. The first step toward the creation of uniform labour legislation was made by the provisional ordinance of January 24, 1919, which, supplementing the divisions of the Civil Code, regulates labour in agricultural and forestry exploitations.[53] Social insurance legislation, such as is found codified in the law of the Empire of July, 1911, _i. e._, as sickness, accident, disability and death insurance, has been supplemented by different provisions, particularly by a law of December 29, 1919, relative to the protection of pregnant women.
