What is the ruling on a female teacher remaining in her home and receiving a salary from her work in a mixed-gender school, and what is the ruling on the salaries she received during this period?

It is not permissible for a woman to teach male students who have reached puberty or are near puberty if there is intermingling, due to the corrupting effects that result from it. It is also not permissible for an employee to receive a salary without performing the required work, except with explicit or implicit permission from the authorized entity. In this case, the female employee must return the money she received, along with repentance. If she is unable to return it, she should donate it to charitable causes.
