Under the law, full-time workers are exceptionally allowed to conclude a part-time employment contract with another employer, but for no more than 8 hours per week, with the prior consent of the employers with whom they are employed full-time, if the work is in a deficit occupation according to the Employment Service, or for educational, cultural, artistic or research work.
That is to say, highly educated people can do complementary work without the control of the Employment Service, but for other occupations this must be certified by the Employment Service as a deficit occupation.
Employers also pay taxes and contributions for the time spent in complementary work. Why is it necessary for lower levels of education to be certified/verified by the institute as a deficit occupation, when perhaps some companies do not need to employ a worker for more than 8 hours a week. Presumably, this extra work could be used to save financially and not to work illegally or through student service referrals. Unfortunately, we are already so far advanced that many people cannot survive on their salary, so I do not see why a certain group of professions is blocked from this possibility of supplementary work.
I would also like to know whether there is any information on how many researchers, teachers, cultural workers, etc. do complementary work in addition to their regular (100%) work. I believe that there is a lot of such work in Slovenia for certain groups.
