I can only tell you that I have it listed on my list of required signage with these comments:
"Required to be visible to job applicants and employees, 42 USC 2000e-10(a). This poster should include five parts, and if not in a combined poster, individual signs must be posted in the manager's office or lobby. The five laws are: Equal Employment Opportunity Act, Fair Labor Standards Act, Employee Polygraph Protection Act, Family Medical Leave Act, and OSHA's Plain Language "It's The Law"."
It isn't something I studied, but if what you believe to be someone applying for a job isn't going through your mail room, it isn't sufficient. The lobby, branch manager or other person who may be doing the interview, etc is where it needs to be.
My opinions are not necessarily my employers.
