Purpose: The aim of the study was to rate the employee’s productivity on different work day organization and to indicate the most optimal work schedule. Design/methodology/approach: For the research presented in this paper, strong literature review was done. We showed why human workforce is so important in tissue culture laboratory and why proper work organization is essential for increasing competitiveness of companies. Literature in the field of overtime work and short, elastic hours of work was also presented. Our research design checked effectiveness of work of ten employees of tissue culture laboratory in five different workday schedules. First combination was control and four other investigated influence of six hour work on main task in different arrangements on productivity. Data was statistically analysed with Kruskal-Wallis ANOVA. Productivity Index and Labour Productivity Index were also used for better results processing. Findings: The highest employees productivity is concentrated in the middle of work day. In conventional eight hour workday, the highest productivity is just after fifteen minute break. Six hour workday has big potential in increasing work, especially when main task is not interrupted by other activities and when work starts at the beginning of workday. Research limitations/implications: In future, research should be expanded on employees efficiency in work with bioreactor and costs analysis of plant production in such system. Practical implications: Our results are directed to plant tissue culture companies and others where employees are essential and their work requires concentration during repetitive activities. We suggest solutions increasing work efficiency. Originality/value: Our work presents hour after hour analysis of work efficiency in different workday organization in plant tissue culture company.

In the paper the problem of personnel allocation under threat was presented. The possibilities of undertaking optimization measures in the process of workers’ health and safety and expenses incurred were emphasized. A mathematical model for this issue has been formulated. An algorithm solving the problem of staff allocation was presented. The evaluation criterion for this assignment was the minimization of worker safety risks. Simultaneous optimization of expenses incurred in the implementation of production tasks was taken into account. The productivity of the staff and all existing jobs with the skills of the employees also was considered. This problem was solved using GNU Octave. The example presented in the paper shows that in case of the most unfavorable allocation of tasks to employees, it will lead to a significant reduction in profits and may increase the risk of undesirable situations. The proposed analysis is the starting point for determining the risk in case of multi-position work.

Purpose: The paper discusses a comprehensive approach to the phenomenon of mobbing within an organization. It shows its characteristics and the causes of this negative phenomenon in an enterprise. It presents the profile of both a mobber and a victim of mobbing. It outlines the course of mobbing, the tactics used in the process and its effects. Design/methodology/approach: Literature research of the subject was carried out. Findings: It also indicates the methods of mobbing prevention, with particular emphasis on the broadly understood prophylaxis, both on the level of organization and the employee. Research limitations/implications: (not applicable) Practical implications: Managerial staff should also develop (or delegate this task to HR or PR department) a program of anti-mobbing activities, taking into account the nature of the organization, improve their qualifications on the management of ethical conflicts, and promote ethical behaviour in the enterprise or institution: promote good practices, appreciate positive behaviour and strongly condemn unethical behaviour. Social implications: Mobbing is a phenomenon that has existed for a long time, but in recent years, in countries where human rights are respected, it was decided to fight this pathology. Originality/value: Mobbing prevention in an enterprise must be a systemic action. First and foremost, it concerns the employer, who should introduce anti-mobbing procedures and immediately react to unacceptable behaviour in the workplace. Employees can also protect themselves from mobbing.

The strategy should be designed in such a way as the risk management can operate not only as a system for avoiding losses, but also risk management should allow recognizing and making use of occasions and create new opportunities for the organization. Risk management includes both an evaluation (analytical and evaluation) undertaking as well as planning and control activities aimed at minimizing (reducing) risk or maintaining it at an acceptable level. Security management can in particular be reduced to the issue of risk management, because risk is a quantitative expression of the functioning of systems in an environment where there are active sources of threats to system security. The article presents the problem of personnel allocation in hazardous conditions, emphasizing the possibilities of undertaking optimization actions in the safety management process. A mathematical model was formulated for this issue. An algorithm solving the problem of personnel allocation is presented. The proposed analysis is the starting point for determining the risk when using multi-station work.

This paper explores how remote work is perceived by young employees. On the basis of literature review, pilot study was undertaken (sample Olson, 1983, DeSanctis, 1984, Bailey, and Kurland, 2002; Madsen, 2011; Grant, Wallace, and Spurgeon, 2013). The results of the pilot study undertaken in Poland confirmed literature findings. It turned out that the most important for young remote workers are: flexible working hours and saving time on commuting to work. The main disadvantages of remote work include: difficulty in separating home affairs from the professional ones, social isolation and greater organizational requirements. The results of pilot study proved that other benefits and drawbacks are irrelevant. An interesting phenomenon is that in the age of social networking and extensive communication tools the second disadvantage of remote working for young remote workers is the risk of social isolation.

Artykuł prezentuje wyniki badań obserwacyjnych, jakie przeprowadzono w jednym ze śląskich przedsiębiorstw produkcyjnych. Badania miały na celu doskonalenie procesu utrzymania ruchu, a skupiły się na analizie wykorzystania czasu pracy przez pracowników. Pomiarów dokonano dla trzech losowo wybranych osób. Zidentyfikowano najważniejsze czynności wykonywane przez pracowników oraz przyporządkowano je do czasu efektywnego – poświęcanego na codzienne obowiązki związane z utrzymywaniem w sprawności środków technicznych, pomocniczego – polegającego na czynnościach o charakterze przygotowawczym i administracyjnym oraz czasu nieefektywnego, w ramach którego pracownicy wykonywali czynności nie mające związku z wykonywaną pracą. Wśród czynności nieefektywnych i pomocniczych wyodrębniono te, których czas był najdłuższy. W celu zmniejszenia ich trwania wykorzystano metodę 5 Why. Dzięki niej rozpoznano przyczyny odpowiedzialne za występowanie zbyt długich czasów trwania czynności pomocniczych. W wyniku przeprowadzonej analizy zaproponowano działania korygujące mające na celu skrócenie czasu wykonywania tych czynności wraz z systemem ich oceny, co w konsekwencji powinno przyczynić się do poprawy efektywności pracy pracowników utrzymania ruchu.

The article presents the results of observational studies conducted in one of Silesian production companies. The research was aimed at improving the maintenance process and focused on the analysis of utilization of working time by the employees. The measurements were taken for three randomly chosen persons. The most important actions performed by the employees were identified and assigned to effective time – spent on everyday duties connected with maintaining the functionality of technical equipment, auxiliary time – dedicated to preparatory and administrative activities, and ineffective time, during which the employees performed actions not connected with their work. Among the ineffective and auxiliary actions those which took the longest were separated. In order to reduce their duration, the 5-Why method was used. It allowed us to identify the causes responsible for the overly long duration of auxiliary actions. As a result of the analysis conducted, corrective measures were proposed aimed at reducing the duration of those actions along with a system for their assessment, which should lead to an improvement in the efficiency of maintenance department employees.

The article presents the results of analysis, the use of continuous flow of logic at the stage of production planning and control of the company producing furniture. The concept of continuous flow tends to regulate the flow of materials in a manner that provides the shortest flow path without unnecessary activities (Muda is a Japanese word meaning waste), a constant takt and defined throughput at constant resource requirements for the so-called transfer of material through the whole process. In the study Glenday’d sieve method was used to identify the correct area, which requires the value stream mapping, and areas called excessive complexity, which do not provide added value. The use of Glenday’s sieve method made it possible to identify areas in which it must be improve production capacity.

It has become almost impossible to have engineering and construction projects completed within the initial time and cost; this is a result of many factors the industry is being plagued with ranging from estimating time and cost. This paper presents strategic methodology that fosters effective engineering and construction projects management with respect to duration/time - cost. The project success is a two-faced phenomenon. On the one hand, project success can be approached from a triangular point of view of project objectives. Performance, cost, time, quality, and safety of a given particular project should be in accordance with the strategic objectives of work logics and methodology at the workflow organization. The main objective of this research is to develop methodology that will help company or individual construction practitioners achieve profitable objectives in the execution of construction projects. For this reason, use of multiple methods of work organization and their competitive model involving several considerations of a wide range of factors, (besides profit maximization and competition) that affect the margin-size decision; use of qualitative and subjective appropriate work organization, to more realistically capture the decision-making process were suggested. The defined optimum construction project works duration should be made in view of all major influential factors as pointed out in this paper (determinate and indeterminate) resulting into deviation of the estimated time and budget cost. At the consideration of the factors the most likely project duration time and it corresponding cost should be regulated (controlled) and some part of the estimates should be saved in form of insurance, and consequently profitable project would be achieved despite the influences of all factors affecting the project.
