An official minimum wage is not the only way to create a de facto minimum wage. Welfare subsidies is another. Strong unions is yet another. High contributions to medical insurance and pensions paid by the employer is yet yet another.
There are also others way to create high unemployment: making it very risky and expensive to get rid of mishires or to reduce headcount if the company isn't going so well. Making management more difficult once the headcount reaches a certain level (because of unions or the creation of employee boards mandated by law) -- that leads to companies trying to stay below such ceilings. Others would be salaries/pensions/benefits tied to how long one has worked for the same company -- which discourages moves to other companies (that might fit ones personality or talents better -- or that has better management). The housing market also has an influence: there might be opportunities in a different city but how easy is it to move? It is relatively easy if you rent your house or appartment. Not so easy if you own it, especially if selling it means you realize a loss. Lots of laws and regulations in a country influence the structure of the housing market (how liquid it is, what loan types are available, how many people rent instead of owning, etc.).
