As the principal, Miguel is likely responsible for overseeing the performance of the school's staff, which includes teachers like Sofia. Therefore, it is Miguel who would typically conduct Sofia's performance reviews, as part of his administrative duties to ensure the quality of education and the performance of the staff at the school.

Carlos, being Sofia's husband and a counselor at the school, may have a professional relationship with Sofia but not a supervisory one. As a counselor, he would have distinct responsibilities separate from the teachers and would not ordinarily be involved in the performance review process for teachers. 

In terms of influence over Miguel's job, it is unlikely that Carlos would have any direct influence. The principal's employment and performance as the administrative head of the school are generally overseen by higher authorities, such as a school district administration or a board of education. Since Carlos' position as a counselor does not grant him authority in administrative matters pertaining to the principal's role, he would not have influence over decisions related to Miguel's job as the principal.
Miguel is the principal of a local high school. Sofia is a history teacher who works at Miguel's school. Carlos is Sofia's husband, and he also works as a counselor at the same school. Who is likely responsible for conducting Sofia's performance reviews, and would Carlos have influence over the decisions related to Miguel's job as the principal?
