An appendix to Section 80 provides that every wage-earner must carry a labor booklet. The following description of this booklet shows how thoroughly registered and controlled labor is in Sovdepia: 1. Every citizen of the Russian Socialist Federated Soviet Republic, upon assignment to a definite group and category (Section 62 of the present Code), shall receive, free of charge, a labor booklet. _Note._ The form of the labor booklets shall be worked out by the People’s Commissariat of Labor. 2. Each wage-earner, on entering the employment of an enterprise, establishment, or institution employing paid labor, shall present his labor booklet to the management thereof, and on entering the employment of a private individual--to the latter. _Note._ A copy of the labor booklet shall be kept by the management of the enterprise, establishment, institution, or private individual by whom the wage-earner is employed. 3. All work performed by a wage-earner during the normal working-day as well as piece-work or overtime work, and all payments received by him as a wage-earner (remuneration in money or in kind, subsidies from the unemployment and hospital funds), must be entered in his labor booklet. _Note._ In the labor booklet must also be entered the leaves of absence and sick-leave of the wage-earner, as well as the fines imposed on him during and on account of his work. 4. Each entry in the labor booklet must be dated and signed by the person making the entry, and also by the wage-earner (if the latter is literate), who thereby certifies the correctness of the entry. 5. The labor booklet shall contain: (_a_) The name, surname, and date of birth of the wage-earner; (_b_) The name and address of the trades-union of which the wage-earner is a member; (_c_) The group and category to which the wage-earner has been assigned by the valuation commission. 6. Upon the discharge of a wage-earner, his labor booklet shall under no circumstances be withheld from him. Whenever an old booklet is replaced by a new one, the former shall be left in possession of the wage-earner. 7. In case a wage-earner loses his labor booklet, he shall be provided with a new one into which shall be copied all the entries of the lost booklet; in such a case a fee determined by the rules of internal management may be charged to the wage-earner for the new booklet. 8. A wage-earner must present his labor booklet upon the request: (_a_) Of the managers of the enterprise, establishment, or institution where he is employed; (_b_) Of the Department of Labor Distribution; (_c_) Of the trades union; (_d_) Of the officials of workmen’s control and of labor protection; (_e_) Of the insurance offices or institutions acting as such.
