This paper examines the impact of teleworking on employees’ labour productivity and the entity`s management in the condition of global pandemic Covid-19 in Uzbekistan. The epidemiological and dynamic nature of the Covid-19 crisis in which organizations have to adopt a work-from-home policy made this investigation very necessary. When the issue is explained more broadly, this empirical research investigates two significant aspects about teleworking process in organizations in the period of lockdown in Uzbekistan. First, teleworking positively affects employee’ labour productivity and the effectiveness of the entity, and the second teleworking complicates the management activities and affects negatively the socio-emotional environment in the work team. The objectives of the study are to identify whether the process of telework affects positively or negatively the organization’s current labour processes and propose multiple recommendations regarding to improve the telework mechanism for enabling prospective labour concerns in the human resources field of Uzbekistan. To achieve the objectives, a survey research design was adopted. The techniques employed in analyzing the data were quantitative methodology, descriptive statistics and Pearson's correlation coefficient. The results indicated that working from the home policy has a strong and positive relationship with employee’ labour productivity and the effectiveness of the entity if it is measured as a result-oriented rather than activity. It was also found that teleworking has a significant relationship with complicatedness of the management and it brings to the negative socio-emotional environment in the work team. Based on the findings, the researcher concluded that unexpected telecommuting in the period of Covid-19 has both negative and positive impact on employee performance and the entity`s management control.

Topicality and demand of the theme of dissertation. In world practice of informatization, systems of electronic document interchange (EDIS) arc considered and introduced last years not only as systems for automation of manage processes but also as high-grade platforms for creation of uniform information field, so borders of their use, certainly, expands and scientists of the world raises interest to them. In researches of leading scientists of infocommunication technologies the demand of problems of authentic gathering, transfer, analysis, coding of information during formation of office-work documents is allocated for getting of effective technologies raising mobility and productivity of EDIS.
Complex measures undertaken by the Government of Republic of Uzbekistan on development of systems of region-territorial automated management and to creation of uniform information field arc directed on wide introduction of information systems, EDIS, databases (DB) on the basis of modern information-communication technologies. In this connection, working out of new methods to intelligent processing of information resources used for improvement of data transfer quality, allowing effectively to find out and correct errors in structure of electronic document interchange with least material and time expenses, differs a special urgency and, at the same time, remains the unresolved theoretical and applied problem having important economic value.
Requirements to information resources and streams of data transmission as the important factor of efficiency and quality of EDIS functioning arc expressed in providing of stability, integrity, safety and authenticity of the information. One of important among factors is the criterion of authenticity of the information, caused by distortion of transferred messages in infocommunication networks because of failures and refusals of means, any handicaps in communication channels, errors of operators, scanning and recognition systems.
Hence, construction of effective systems to control of information authenticity during transfer and processing represents special scientific interest as priority technology of data processing, characteristic for conditions of automated management and electronic document interchange at the enterprises and organizations.
For existing methods, despite of providing the high level of information transfer authenticity, some unsolved questions is typical, and as basic of them it is possible to allocate the following: at development technologies of electronic documents interchange in structure of modern data transfer packages the significant volume of resource is spent for headings, at the same time the most part of information in headings remains constant from package to package during stream of transfer of the whole frame (redundancy of the information arising at it and mechanisms to provide reliability of deliveries consisting, basically, in sending the appropriate message and repeated transfer of packages, - result to additional time and material expenses while errors detection and elimination); code and hardware methods of information transfer control arc focused, mainly, on elimination the transposition mistakes in managing fields of packages; however, at data transfer there arc also distortions in information fields, which frequently reveal as multiple text mistakes.
In this relation, the decision of tasks for providing of information transfer authenticity is reasonable to consider in two aspects.
Solutions of the first type tasks should taken into account errors of the man-operator, scanning and other devices intended for input of the information. These kinds of mistakes make greatest volume of distortions in text and arise at Applied and Representation levels of OSI model (Open System Interconnection reference model).
Solutions of second type tasks, devoted to control of the information reliability, take into consideration the probability of distortions which occur at stages of Transport, Network, Physical and Line of model OSI.
Demand of the dissertation is characterized by the fact that introduction of a wide range of IP-enabled technologies in electronic document interchange is connected to requiring close attention tasks of detection and correction of errors during preparation and processing of documents.
This research work is focused on providing realization of laws of the Republic of Uzbekistan «On informatization», «On electronic digital signature», «On electronic document», «On electronic commerce», «On electronic payments», Decree of the Cabinet of Ministers of the Republic of Uzbekistan № 126 on 05.04.2011 «About measures on installation and use of a single secured e-mail and system of electronic document interchange in the executive office of cabinet of ministers, bodies of government and economic governance, local government».
Following that, the solution of listed tasks requires carrying out the special researches and development connected to creation of methods and algorithms, capable to control the information authenticity in structure of data transfer packages at the expense of use the enclosed redundancy, and able to function in transport environment, eliminating existing lacks. This fact causes necessity of allocation of a special class algorithms for providing of information authenticity on the basis of new type of PR-rcdundancy (property redundancy), defined by depending on properties of processed object.
Purpose of research is development ol constructive methods, models, algorithms and systems of information authenticity control during transfer and processing of the data on the basis of mechanisms used PR-rcdundancy of various nature, and software and algorithmic realization of results for developing technologies of electronic document interchange.
