One SOPA Sweep is equal to the volume of public outrage and ridicule needed to reverse the certain passage of an abusive bill into law, kill it and at least one similar bill (the Senate's Protect IP Act) so decisively as to leave supporters too shocked and wary to make similar efforts during the same legislative session.
SOPA Sweep quantifications are similar to percentages in that the seminal Sweep carries a numerical value of 1.0, in keeping with its status as the gold standard of consumer-protecting surges of public outrage. Reversing legislation to make Facebook peeping legal would, as a rough estimate, equal approximately .35 SOPA Sweeps [.35SS] – Just in case you were wondering.
No matter how much smack an employee might talk in private, what opinions they express at home that they can't discuss in the office, no matter how many long-distance virtual "friendships" they maintain with people of whom the employer disapproves, no employer has the right to monitor or control the behavior of employees in their personal lives.
Personal Facebook accounts – not public accounts created as a way to contact customers or create a public image for the company – are part of an employee's personal life and should be off limits to employers, no matter how entitled they feel to violate the personal boundaries of employees.
Pretend you can and you might as well start a job interview by demanding employees dump out their wallets or purses so you can rifle through them, or give up their house keys so you can go snoop through their bathrooms to see if they use all the right toothpaste or antiperspirant.
'Personal life' means 'personal,' not 'waiting for the approval of management'
That kind of behavior, that contemptuous dismissal of the rights of the individual, that blatant disregard for manners, rights or propriety is the kind of thing for which state prison systems are regularly pilloried when they do things like that to prisoners.
When they or any other organization does it to their employees, there's no way to forgive it, no way to justify even the attitude that would allow it and absolutely no other way but one to answer the question.
Should employers be able to demand access to Facebook or the other social-networking sites used by current or prospective employees?
Sure. Right after the interviewer submits to daily invasive strip searches to confirm they're not carrying secret copies of 'How to Abuse Your Position and Employees For Fun and Profit,' or 'The Robber Baron's Guide to Class Warfare and Worker Intimidation.'
