"Osnovna organizacija udruženog rada" - Basic organization of united labor - was the smallest economic unit in the last 16 years of SFRY (actually shorter, they went back to enterprises in mid eighties, so effectively ten). There was one larger, "SOUR" - složena, i.e. complex OUR. OURs were independent, even when members of the same SOUR, and didn't even have any obligation to the rest of it, including when the SOUR was its founder and investor. Which altogether made the life interesting in those years.
The system where everybody was either in an OOUR or in a SIZ (samoupravna interesna zajednica - selfmanaged interest community, i.e. the non-producing services) led to various paradoxes. When high schools were reorganized into "vocationally directed upbringing and education" (9th and 10th grade) and "vocationally directed education and upbringing" (11th and optionally 12th), they stayed in the same buildings where they were before, but they now had two staff rooms, two bank accounts, two principals (actually CEOs), two payrolls - because they were separate OOURs. After a few years, new people from one unit barely knew those from the other, because they practically never met.
The schools were reunited in 1983. The rest of the economy kept plowing in separate OOURs until the end. Maybe it was a good idea to have them, but it was definitely done wrong.
