Every employee in the of Montenegro enjoys certain employment rights. Among others, this includes the rights to earnings, safety at work, health care, personal integrity protection, dignity of personality, rights due to temporary illnesses due to illness, loss of working ability, age and material compensation due to temporary hindrance. In this regard, special rights are enjoyed by employed women during pregnancy and childbirth, then minors who are employed and persons with disabilities. Also, employees in the of Montenegro are entitled to contributions for compulsory social security, which provide funds for the financing of compulsory social insurance, which includes pension and disability insurance, health insurance and insurance in the case of temporary unemployment. Unfortunately, practice proves that these workers' rights are often ignored. Therefore, the notion of work on the black, which is actually a form of exploitation of labor, is created, works with a compensation below the envisaged minimum, without contribution for compulsory social security. From that, problems arise, which will be dealt with separately in this paper, relating to the safety of workers in black and increasingly often unfortunate cases, with a mortal epilogue for working people.
