My response:
Okay, I may have "jumped the gun" a little too quickly. However, I wasn't completely mistaken either.
Here's the law - -
California Labor Code section 432.2
(a) No employer shall demand or require any applicant for
employment or prospective employment or any employee to submit to or
take a polygraph, lie detector or similar test or examination as a
condition of employment or continued employment. The prohibition of
this section does not apply to the federal government or any agency
thereof or the state government or any agency or local subdivision
thereof, including, but not limited to, counties, cities and
counties, cities, districts, authorities, and agencies.
(b) No employer shall request any person to take such a test, or
administer such a test, without first advising the person in writing
at the time the test is to be administered of the rights guaranteed
by this section.
Employee Polygraph Protection Act (29 USCA § 2001 et seq.), enacted in 1988, generally prohibiting private employers from using lie detector tests for preemployment screening except in some security and pharmaceutical businesses, or during employment except in limited circumstances involving an ongoing theft investigation.
These privacy claims may arise from:
• monitoring and audio/video recording of employees in the workplace;
• monitoring employees' e-mail or use of company computers for personal business;
• searches of computer files;
• searches of an employee's physical person or purse, or workplace lockers, desks and company cars;
• credit checks on applicants and employees;
• psychological testing of applicants and employees;
• disclosure of employee personnel records to third parties;
• mandatory polygraph examinations
Alright, let's assume that the employer says in writing, "Hey, Joe. You won't be fired if you refuse the polygraph test." Then, the employee "refuses" the test after the employer "first advis[es] the person in writing at the time the test is to be administered of the rights guaranteed by this section."
Now, since California is an "At-Will" State, how many reasons can you come up with to fire this employee next week?
So, the law is a hollow law, inviting the employer to come up with any reason s/he wants, or no reason at all. As long as the employer swears that the refusal and the firing are not connected in any manner, then the employer hasn't violated any law.
Bottom Line?
If a California employer want to fire you, you're fired - - and there's nothing you can do to stop it.
