Side part-time jobs can be very useful in many ways. Here is a list of who they are a good way to make money for:
-Students
-Teens from age 13 (e.g. delivering flyers)

-Retail
-Nurseries and garden centers

Actually in a great many fields, but these are the ones that came to mind spontaneously. When looking for side part-time jobs, you can lean heavily on unsolicited applications, which are very popular with many employers. When searching for jobs online, be careful, as there are also many dubious offers. It's important that you don't have to pay anything up front, financially speaking. And that you can also find a contact person and a company address.
Why do people look for side part-time jobs?

-Financial shortfalls
-To save or invest money for special purchases
-To find out professionally what suits you
-For mothers after parental leave, to make returning to work easier
-To top up retirement income
-To make it easier for the unemployed to return to work
-To improve self-confidence among the long-term unemployed
-To finance a degree or make further training possible
-To furnish your first own apartment
The list could go on endlessly. There are in any case many advantages to going after a part-time job. Today everyone needs money on the side. But I would rather focus the search on businesses in your area.
There are short-term part-time jobs, open-ended ones and long-term ones. Some part-time jobs can, under certain circumstances, turn into full-time or part-time positions. That's how you've made your way out of unemployment. In Germany, jobs that don't exceed 450 euros per month are exempt from social security contributions. If you have several mini-jobs up to 450 euros, the second becomes subject to social security contributions, while the first stays exempt.
Seasonal workers in agriculture or hospitality, e.g. at a beer garden, are also good sources of income, and you have the prospect of being able to work there again next season. For open-ended employment, entitlement to vacation and sick pay applies just as in any other employment. It makes no difference whether it is a part-time job or an employment relationship subject to social security.

These jobs are also well suited to avoid becoming isolated while unemployed, to gain new experiences, and to feel like a contributing member of society. That is an important contribution to a stable mind. Everyone somehow wants the feeling of belonging and of achieving something that benefits others.
Part-time jobs have drawbacks, but also a great many advantages, as you can read here.
Good luck in your search for a suitable part-time job.
