Limit Employer Profiling

Employers can too easily abuse data they can obtain on potential or current employees not to hire the best worker but to screen out those with the "wrong" opinions or other characteristics irrelevant to the skills need for the job.  Most dangerously, people likely to demand better treatment in the workplace or who might join a union can be screened out, lowering wages in that workplace and, as such practices are compounded across most workplaces, systematically increase economic inequality.  

Policymakers should ban or restrict employers from using any data except that most relevant to the position a company is hiring for in order to ensure both employee privacy and that people aren't punished for free speech and freedom of association before they ever get a job in the first place.
