The condition of in-work poverty has an impact on the wellbeing of people. Thus, a deterioration of mental and physical health related with this form of precariousness has been observed
[11]. A relationship has also been shown between the deterioration of perceived overall health and poverty
[12][13]. This relationship is stronger in the case of women
[12]. Similarly, factors related to occupational health are affected in a context of in-work poverty. Bearing in mind that in-work poverty is linked to more precarious positions, characteristic of micro-companies, the poor development of occupational health and safety in these contexts leads to a deterioration of wellbeing
[11][14]. What is more, despite the fact that the condition of poverty negatively affects health, these people tend to use healthcare systems less. In countries where healthcare is not universally covered by public systems, this deficit in the use of primary care is mainly due to economic factors
[14]. For example, in Canada a lesser degree of use of dental care—not fully covered in the national healthcare system—is observed.
[15]. However, in countries where the healthcare system offers universal coverage there is also less use of them by people experiencing in-work poverty
[11]. This is explained by the fact that these people cannot afford to abandon their employment obligations, or risk losing their jobs. This situation leads to a vicious circle between the condition of in-work poverty and deteriorating health.
The scientific literature on social exclusion shows that a situation of poverty is linked to mental health symptoms, as well as increased consumption of psychopharmaceuticals
[16]. Similar results can be observed with a situation of precarious work in a broader sense
[17]. When trying to limit the phenomenon studied explicitly to in-work poverty, there is not a large number of studies that specifically address this matter. Attempting to mention some of them, Moon and Sangjun
[18] detect a higher prevalence of depression in situations of in-work poverty. Similarly, they link this employment situation with an increase in the consumption of alcohol, which intensifies the mental disorder experienced. As for the conditions of this relationship, they point out the inability to afford housing-related expenses, and show that it clearly affects women more than men.
A study carried out in Spain presents the same conclusion as Moon and Sangjun
[18], pointing out that the general state of mental health of people experiencing in-work poverty is the same as those who are unemployed, while in both cases there is a deterioration with respect to the people who are in a normalised employment situation
[19]. Likewise, chronic stress is linked to situations of in-work poverty given the uncertain living conditions that these families experience
[19][20].
