Abstract: Background: Literature defines different types of flexibility and security with regard to work. Regardless of which type of flexibility or security is discussed, the consequences for individuals, organizations or employers and society are significant.
Purpose: The purpose of the research was to compare and analyse the correlation between the different types of flexibility and security in work and organizational efficiency.
Methodology: Data was gathered using the Computer-Assisted Web Interview (CAWI) method. A link to an online questionnaire was e-mailed to randomly selected organisations across all economic sectors in Slovenia that had a published e-mail address, either in business directories or on a company website. We asked them to forward our e-mail to their employees. The correlation between different variables was used for data analysis.
Results: The results of our research show that there is a low positive level of correlation between different types of flexibility and security in the context of work and also between different types of flexibility in work and organizational efficiency. The correlation between different types of security in work and organizational efficiency is positive and medium strong.
Conclusion: It is recommended that the legislators be aware of the importance of their correlation with organizational efficiency when preparing legislative amendments regarding introduction of the flexibility and security in the field of work.

Multi-objective synthesis of company’s supply-networks based on integration of renewable resourcesAnnamaria Vujanović
, 2017, doctoral dissertation
Abstract: The aim of this doctoral dissertation was to develop a general methodology for sustainable integration of company's supply networks into nearby regional networks by i) integrating renewables, thereby increasing company's energy self-sufficiency, ii) by performing multi-objective synthesis in order to obtain economically efficient and yet environmentally benign or even unburdening solutions, and iii) to perform dynamic and stochastic synthesis under uncertainties in dynamically changing market conditions in order to obtain more reliable and realistic solutions. The research work is directly interlinked with a large-scale European meat producing company Perutnina Ptuj d.d., which is located in the heart of Slovenia.
The aim of the first part was to integrate renewables into companies’ supply-networks at regional level in order to maximize the self-sufficiencies of their energy supplies. This concerns companies’ activities from the use of natural resources to supplying their final products to the customers being interlinked with their regional networks. A Mixed-Integer Linear Programming (MILP) model has been developed for the integration of both the companies’ and surrounding regional supply-networks and the utilization of different types of renewables as sources for the companies’ energy supplies. The potential renewable energy sources, which are located within companies surrounding region are solar, biomass, organic and animal wastes. The result indicates that by sufficient integration of renewables into companies’ supply networks, profitable and yet energy self-sufficient solutions can be obtained.
The second part presents the multi-objective synthesis of a company’s supply-network by integrating renewables and accounting for several environmental footprints. A previously developed model for achieving energy self-sufficiency by integrating renewables into companies’ supply-networks has been extended for the evaluation of environmental impacts, such as energy, carbon, nitrogen, and water footprints. The achievement of an energy self-sufficient supply-network has been considered whilst significantly reducing environmental impacts. Direct (burdening) and indirect (unburdening) effects that form total effects on the environment are considered for the evaluation of environmental footprints. This approach identifies those alternative energy production technologies that are more profitable and environmentally more benign with significant unburdening capabilities. The results showed significant unburdening of the environment in terms of carbon and nitrogen footprints; however, higher burdening in terms of the water footprint.
The third part presents a multi-objective MILP synthesis of a dynamic supply-network under uncertainty applied to the company. The previously-developed multi-objective model for achieving energy self-sufficiency by integrating renewables into companies’ supply-networks has now been extended to account for the dynamic consideration of variable supply and demand over the year, for uncertainties related to products’ demand and sun radiation, and for multi-objective optimisation, in order to obtain the most sustainable company’s supply-network. The sustainable synthesis of a company’s network is performed regarding the integration of the renewables such as biomass and other wastes, and solar energy. The obtained solutions are those reflecting maximal profit, reflecting constantly-changing dynamic market conditions, accounting for several uncertain parameters, and protecting the environment.

Abstract: The purpose of this paper was to determine whether tipping could reduce labour costs in the petroleum products retail sector. The research we present was designed on the basis of survey results gathered from Slovenian petrol stations in 2009 and 2010. We have identified the following factors in the tipping process: job satisfaction, flexibility, service quality, satisfaction, motivation and the factor of receiving tips. The analysis showed correlation between methods used to increase the value of tips and better service quality, increased financial and numerical flexibility, motivation, satisfaction upon receipt of tips and the method used to increase the value of tips. In order to decrease labour costs we propose that the management take control of tipping and integrates tips into the reward system. Also, the employees should be made aware about how tipping improves service and increases their income.

Flexicurity or flexicarity?Noemia Bessa Vilela

, 2016, original scientific article
Abstract: Due to the increasing competition on the labour market, the search for new approaches to labour legislations led to the creation and adoption, in some countries, of so called “flexicurity”. “Flexicurity” became top of the list in the policy agenda in the European Union, but there is doubt that such an agenda for encompassing labour market reform providing not employment. As sources are used “flexicurity” models, in countries where it has already been successfully implemented, as well as Eurostat data, information made available by the European Commission, as well as doctrinal and research papers. Portuguese jurisdiction is considered by national legal doctrine as a closed model. Heavy regulation and constitutional constraints drive an almost unanimous rejection of the possibility to introduce the concept at national level. This article's goal is to discuss the ways the concept could be introduced in the Portuguese jurisdiction. Would the model effectively create security, or would it result in precarity?

, 2018, review article
Abstract: Background and Purpose: Part-time employment could be seen as a modern form of employment or a type of innovative organizational change. The average share of part-time jobs in the Czech Republic in the observed period of 2004-2016 was 3.9 % according to the OECD, in comparison to the average OECD value of 16.6%. The main question to arise was, are there any regional differences? The presented conclusions are based on a regional study in the Moravian-Silesian Region (MSR) in the Czech Republic where the median value of part- time jobs is 10%. The main goal is to evaluate the regional level of part-time job offers and identify the main opportunities and obstacles which cause the low number of these job positions.
Design/Methodology/Approach: The paper is based on a quantitative study using a questionnaire-based survey, comprising 215 respondents – owners of small and medium-sized enterprises (SMEs) in the Moravian-Silesian Re- gion in the Czech Republic. The survey consists of 16 questions in three main areas: (i) Entrepreneurial motivation (1 item), (ii) External factors – Labour market problems (4 items), and (iii) Internal factors. Secondary information such as the results of earlier studies and regional government websites were used for data results comparison. All variables are compared in the context of the branch of business, number of employees, turnover, and age. Finally, a factor analysis was used to find the main way how to improve part-time job offers.
Results: The variety of businesses and different regional locations opens up space for discussion regarding part- time job support. A factor analysis found five significant issues, which could affect local labour market and company behaviour.
Conclusion: The added value of the paper can be seen in the factor identification, where internal willingness to sup- port part-time employment and qualification growth as organizational change must be in first place.
