Employers routinely subject applicants to personality tests, IQ tests, fitness tests for jobs that have nothing to do with manual labor (essentially age/gender discrimination), background checks, credit checks even when the job doesn't involve handling money, and yes, looking them up on social media. Do people really want to work for these places? Yes, because they need to pay their rent, and don't have the nestegg of a well-paid Silicon Valley software developer, or recruiters chasing them to offer them work.
The sense of free will is an illusion of physics and consciousness; choices are made by quasi-deterministic electrochemical processes before our conscious minds are ever aware of them.
