Today's labor market is characterized by flexibility. This applies to organizations, forms of employment and working time. Unregulated working time is such an adaptation and the main subject of this essay. The purpose of this study was to investigate the conditions that underpin unregulated working time, in relation to the Swedish legislation and to EU legislation. The intention has been to investigate the work environment impacts of unregulated working time, and what differences there are from a gender perspective. The conclusion is that workers who enter into agreements for unregulated working time have significantly different terms from traditional workers. Workers with unregulated working time are exempted from the working time law and so even the provided safety net. A frequent part in agreements of unregulated working time also means that the employee agrees to an elimination of compensation for overtime work.Unregulated working time is appropriate for workers who have working tasks that they can adjust to their working time. Workers with controlled working tasks have not the same opportunity, which increases the risk of perceived ill health. Unregulated working time is therefore not suitable for all forms of employment. More scientific research is needed in this area, but based on the available scientific research, there are indications to suggest that women are overrepresented among those occupations. It would then also mean that womenare at greater risk of ill health than men.

Syftet med föreliggande studie var att undersöka upplevelsen av den psykosociala arbetsmiljön beroende av anställningsform och kön. Datainsamlig genomfördes med ett nyutvecklat frågeformulär (EPA), som är baserat på de senaste föreskrifterna gällande organisatorisk och social arbetsmiljö. EPA bestod av sju moduler; arbetsbelastning, arbetsorganisation, handlingsutrymme, kunskap och utveckling, ledarskap, stöd samt återhämtning. I studien deltog 80 personer, 40 personer hade reglerad arbetstid som jämfördes med 38 personer som hade oreglerad arbetstid,  35 var män och 45 var kvinnor. Resultatet visade att de med oreglerad arbetstid upplevde den psykosociala arbetsmiljön något bättre men det var inte statistiskt signifikant. Männen upplevde den psykosociala arbetsmiljön bättre än kvinnorna men det fanns ingen statistisk signifikant skillnad.  För modul ledarskap fanns en statistiskt signifikant skillnad mellan könen, där männen upplevde ledarskapet bättre. Vidare förelåg inga skillnader i arbetsmiljön beroende på anställningsform eller kön. / The aim with the present study was to study the psychosocial work environment depending on employment and sex with a newly developed questionnaire (EPA), which was based on the latest regulations regarding organizational and social work environment. The questionnaire consisted of seven modules; workload, work organization, margin of action, leadership, support, knowledge and development and recuperation. In this study 80 persons participated, 40 of them had regulated working hours and 38 had unregulated working hours, 35 were men and 45 were women. The results of the study showed that persons with unregulated working hours experienced the work environment slightly better, but the result was not statistic significant. Men experienced the work environment better then women, but the result was not statistic significant. There was a statistic significant difference though, in module leadership, showing that men had a better experience of leadership. Further, the result showed that there was no diffrences in the workenvironment depending on employment and sex.
