I'm sorry, but while I follow your thinking, that if the employer has listed some jobs as overtime mandatory, that the employer must
do the same for each position that might entail overtime, this is not the sort of thing that can be legally enforced, or for which there are present laws requiring such notice.
The law simply does not mandate that an employer classify jobs in that manner---so the employer voluntarily classifying some of them will just not result in any corresponding legal obligation to do that for all job descriptions.
I already did consider a discrimination view of your situation---but under the laws of CA and the feds, unless you can show that the discriminatory effect is based on a person's Ethnicity, Color, Religion, National Origin, Age, Sex, or Disability, then you just don't have unlawful discrimination---something that you would have a legal remedy for.
I'm sorry, I understand, and empathize, with your situation, but as CA is far and above the state with the greatest amount of pro-employee laws and regulations, if any state had such a requirement---it would be CA.
The law only mandates, that for the vast majority of occupations, the employer may demand overtime of any employee, without prior notice of that possibility---so long as the overtime wage laws are abided by. And for employees who are salary exempt---they can be ordered to work more than 8 hours in a day and more than 40 in a week without any
I wish you the best in 2011.
