Labor running the company? This fails more often than it succeeds. Bread and circuses are the result, then bankruptcy. Indeed obvious without the use of hindsight.
I'm not interested in debating the merits or lack thereof of socialism as a system of government, but the "bread and circuses" thing applied to Roman citizens.
Unless I was misinformed, the overlap between the people in the Roman empire who were citizens and the people in the Roman empire who were the labour force was very, very small.
So, executive boards of companies?
The positive aspect is that it introduces democracy into the system (through control by officeholders), if only for the moment that it takes for power to recentralize (as any autonomy that the business has is lost due to patronage appointments from the central government or larger unions.) Maybe this could be prevented by handing control to the union of the workers in a particular company, or a particular location, rather than large unions that cover entire industries.

I recall VW put a single member of labor on their board; it broke the company as other members courted the vote of the uninformed labor rep, giving up perks until labor costs were bankrupting the place.
Companies operating in a competitive environment have to be pretty efficient. Optimizing a company for employee benefits is pretty much at odds with that. I know, they will all be more loyal etc. But that's different from lowering product cost and controlling profit margins. You fail to make payroll even one week, the game's over.
Of course, since labor representation on boards is widespread in Germany, most medium to large German businesses are a good example. I assume the German economy is in tatters.
If we presuppose educated and trained labor members who are used in management, well then I guess we have that now? In every company everywhere.
