My daughter did a one-year MA program in English secondary education three years ago at a private university in California, which included a preliminary California teaching credential. (In California, teachers must “clear” the credential within 5 years; public schools generally provide the opportunity for new teachers to participate in a 2-year induction program to clear the credential). Jobs at the time were plentiful and continue to be for her and her cohort, especially if one is willing to teach in a lower socio-economic school or district. Many of her cohort received more than one offer, and continue to be employed as teachers. What happened in San Diego with pink slips is unfortunate,though not common at this time, it seems. In general, California is experiencing a severe teacher shortage, particularly in less desirable districts, in STEM fields AND English/drama/humanities. So, to the OP, dig further into the teaching situation in California before deciding against it.
