Yes! I was just thinking of this. My thinking started along the lines of tech workers getting together to apply for jobs, discussing who would be best for each role etc, so instead of each role getting 100 varying quality applications it gets just one reasonable application that the company can take or leave.

Then I made a couple of obvious leaps and realised I was quickly converging on existing ideas like unions, and then guilds.

Does anyone know why guilds stopped being a thing? One possibility that comes to mind is that having a third party (the guild) involved in the employer/employee relationship would make things awkward and it might eventually seem unnecessary as the relationship developed -- although this would be a pretense obviously, as the employee is ultimately disposable as far as the company is concerned.

Obviously unions are popular, but they don't seem to go very far in terms of being involved in the whole process of work -- deciding who is going to work where, what the terms will be, etc.
