Application of Federal Law

Employers in California are subject to both federal and state minimum wage requirements. However, since California law is stricter and requires a higher wage, the California minimum wage must be paid.
Employees Cannot Agree To Work For Less

Although some employees may desire to work for less than the minimum wage in order to secure employment, any agreement to work for less than the minimum wage is against public policy and is void. Even if such an agreement exists, the employer must pay the employee the required minimum wage.

Exceptions to the Minimum Wage Law
Training Employees

An exception to the minimum wage exists for learners, who may be paid not less than 85% of the minimum wage rounded to the nearest nickel during their first 160 hours of employment. A learner is someone in an occupation in which they have no previous similar or related experience. A learner can be any age and is not limited to teenagers.
Outside Salespersons

Outside salespersons are not subject to California's minimum wage law.
Parent, Spouse, or Child of Employer

Parents, spouses, and children of employers are not subject to California's minimum wage law.

I'm not sure of the point behind your soliloquy, but the minum wage rate in California is not $6.75/hour, rather it is $7.50/hour.

I suspect the point behind this is to get posters to hire his firm. But as long as he does not actively promote it and limits himself to including a link to his website in his signature, I'll allow it.

FYI. CA minimum wage used to be $6.75/hr, but went to $7.50/hr in 2007 and is scheduled to go to $8.00 in 2008. Most Exempt Salaried employees under federal (FLSA) rules must be paid a salary of at least $455/week, but California requires Salaried Exempt to be paid at least twice their minimum wage ($600/week in 2007 and $640/week in 2008).

Maybe this is just me, but a firm who apparently fails to keep track of legal changes might not want to advertise that.

No, it's me, too. You just said it first. ;)
