Mondragon corporation has existed in spain since the 1950s as a worker-owned cooperative and employs about 75,000 people. Whole foods employs about 91,000 but I'd say that puts them in the same ballpark. You could argue in addition that Mondragon has been limited by a) Spain having been a dictatorship until the 1980s, b) the relative youth of the EU single market vs that of the US leading to a more regional business culture and c) the additional language barriers in Europe that make business expansion a bit slower than in the US.
