As a part of organization of overtime work, working in day off and working on public holidays managers need to prepare a package of documents for employees. At first this work was carried out in MS Word and took a lot of time. Then more convenient form of accounting in MS Excel was developed, and from 2015 application form and order can be downloaded automatically from 1C. In a greater degree these changes have influenced work of managers on production site, especially during the periods of mass overtimes.
