My school system (not in California) does not have any such claims in their employment contract, but does include such language in their Acceptable Use Policy for the computers and the school network - they claim anything stored on the school network is theirs. This has made me much more reluctant to put anything I create onto the network, but the part I find funny (and amazing) is that there is plenty of commercial stuff stored on our network servers for use by the teachers - videos from educational companies, Advanced Placement test materials, etc. I'm pretty sure the Educational Testing Service would object to my school claiming ownership over an AP test they have copyright to, and I'm sure the video companies would for their materials. This is the ridiculous level the f--ing lawyers and our copyright laws have brought us too - Orwellian newspeak meanings to our language (WE own it ALL!), OR, everyone is guilty, period (of course, the whole point of Orwellian newspeak was that everyone was, indeed, guilty, unless OK'd by Big Brother).
