A California teacher on medical leave for breast cancer treatment has to pay for not only her medical bills, but for the substitute who is teaching her students while she’s out of the classroom.

Due to a state policy, all teachers receive ten days of paid sick leave. Anything beyond that, for another 100 sick days, the cost of the substitute teacher will be deducted from the teachers salary.

Beyond that, teachers are able to pull from a bank of donated time, up to 85 days without a deduction from their paycheck.

The average daily cost for a substitute in San Francisco is $203.16, says school district spokeswoman Laura Dudnick.

The average teacher salary in the district $82,024.27, not including benefits. The national average public school teacher salary in the US is $58,353.

Getty Images California's super-bloom draws influencers to Lake Elsinore People pose for a picture among wildflowers in bloom Monday, March 18, 2019, in Lake Elsinore, Calif. About 150,000 people flocked over the weekend to see this year's rain-fed flaming orange patches of poppies lighting up the hillsides near Lake Elsinore, a city of about 60,000 residents. The crowds became so bad Sunday that Lake Elsinore officials closed access to poppy-blanketed Walker Canyon. By Monday the #poppyshutdown announced by the city on Twitter was over and the road to the canyon was re-opened. AP

“This reflects California Education Code language related to extended sick leave that applies to all other school districts in California,” Ms Dudnick said, in a statement referring to the 1976 law the policy is rooted in.

“This is not unique to San Francisco. This is not a district-only rule.”

The teacher is choosing to remain anonymous to protect her privacy during a trying time, but district parents are coming forward to contest what they see as an unfair policy.

District parent Elia Hernandez told CNN: “She’s an incredible teacher and that’s not fair. That’s crazy!” regarding the policy. Another parent, Abby Hipps, said: “She’s one of the best teachers. It’s terrible.”
