(CNN) A San Francisco teacher who is on medical leave has to worry about more than just battling breast cancer. On top of footing medical bills, she has to pay for a substitute teacher at Glen Park Elementary School. All teachers receive 10 paid days of medical leave a year in the San Francisco United School District . Under a 1976 California law , the cost for the substitute teacher will be deducted from the teacher's salary. The average daily cost of a substitute teacher in San Francisco is $203.16, San Francisco United School District spokeswoman Laura Dudnick said.
