The paper defines the key features of working from home as a form of flexible work arrangement and systematizes and compares the most commonly used forms of flexible work arrangements and their synonyms. The focus of this thesis is the introduction of work from home during a pandemic and its impact on employees and employers. An empirical study was conducted on a sample of 131 employees in the Republic of Croatia and the aim of the study was to investigate the effects of working from home, advantages and disadvantages of working from home, employee attitudes and quality of life, productivity and work-life balance during work from home during COVID -19 pandemics. The paper additionally investigates the differences in the attitudes of public and private sector employees. The survey found that 88.5% of respondents, during the COVID-19 pandemic, worked full time from home. Furthermore, 71% of the respondents in the survey stated that they still want to work from home, while 75.6% of them confirmed that the transition from work in the workplace to work from home went smoothly. Respondents viewed positively the possibility of working outside the prescribed working hours and the excess of free time that arose as a result of the absence of the need to travel to work. The research showed a significant difference in the attitudes of public and private sector employees, with public sector employees being significantly more inclined to claim that they worked more hours on average than in the pre-pandemic period, did less work than usual, that their job was more demanding, and how they were not well enough prepared to work from home.
