The closest analogue that occurs to me would be an apprentices' guild, that would represent their interests against the established master craftsmen.
'Popular Guilds' that are exactly what you described cropped up across the German states in the mid-19th century, but most were crushed either through state or noble action or through the cultural backlash against the 1848 revolutionaries, of which most popular guilds supported. Have the revolutions go another way and perhaps you get what the OP is going for.
Well, i agree that the popular guild could have been transformed themselves as unions. But 1)you'll agree that they're not really the medieval guilds that Once asked for, 2)they'll not remplace unions but more likely, under the foreign influence, transform thelselves in regular ones.

Unlikely if you keep the medieval organisation of guild. It's a very hierarchical organisation, more close to modern trusts that have social issues in order to kept the trade organized that unions.
Basically, it would maybe evolve like an union diriged by owners, so not very effective, and less interesting as patronizing or paternalism for business.
Not always. A lot of guilds represented people who were more akin to skilled laborers, such as masons and craftsmen. They tended to be contract laborers, rather than wage laborers though. But i could see under the right circumstances those guilds surviving.Keeping guilds around, though with much less political power and no monopoly, shouldn't be too difficult. Turning them into labour unions is however, since guilds are essentially made up by small business owners and a guild representing employees, while possible, would not be a guild in any traditional sense and would have to be newly created rather than reformed from an existing one.
