LEBANON, Tenn. – When a principal makes an announcement over the school public address system, asking people to stop putting lotion on doorknobs, stealing teachers’ keys and moving their cars, it’s a pretty good bet that the culprits are students.

But that wasn’t the case at Tuckers Crossroads School in the Wilson County, Tennessee school district.

A teacher and two other school employees have been accused of playing those “pranks” on fellow staff members on May 28, when classes were apparently not in session, and the teacher is now unemployed as a result.

The Wilson County school board voted unanimously Monday to fire tenured teacher Matt Mock for allegedly participating in the pranks, according to the Lebanon Democrat. The board’s decision came despite “two emotional testimonies” from Mock’s supporters, the newspaper said.

Mock and the other school employees spend a good part of the day outside of the classroom of Anna Raines, the only black teacher in the school, the news report said. They repeatedly greased the doorknob of Raines’ classroom, as well as a teachers lounge door, the report said.

“The three stood outside of her room and began targeting this African-American teacher,” Donna Wright, the distict’s director of schools, reportedly told the school board. “One of the three employees came into the room pretending to ask her questions but at the same time, smearing the inside of her door handle, as well.

“The video from this day shows Mr. Mock and the two other school employees in the hallway outside this teacher’s room for a large majority of the time between 12:40 and 3 p.m.,” Wright was quoted as saying by the newspaper.

Wright told the school board that the teacher locked herself in her classroom, turned out the lights and contacted another teacher about the situation, because she was upset, according to the news report.

Later the teacher left her room, locked it and went to work with another teacher, the news report said. On her way out Mock allegedly told her her that she had “made out pretty good today,” Wright told the school board.

According to the newspaper, “Wright said Mock, after making sure no one was looking, unlocked the teacher’s room with a master key and moved a desk to block the inside of doorway and placed a student desk on the teacher’s desk.

“Mock allegedly took keys off another teacher’s desk and refused to return them to her when she asked, according to Wright’s charges. Wright said the teacher said she followed Mock down the hallway and repeatedly asked for the keys, which Mock used to move the teacher’s car.

“However, Wright said students in the building that day claimed Mock told them to take the keys, and the teacher’s car was moved to middle school side of the building.

“Wright said Mock used a master key multiple times to open doors, which was locked by the teachers to whom the rooms were assigned.

“Wright said Mock violated several district and federal policies, which included Wilson County policy 5.500 relating to discrimination and Wilson County policy 5.600 regarding professionalism, neglect of duty and insubordination.”

Wright told the school board that, “At some point during this time, the principal came on over the speaker and made an announcement that the people putting lotion over the doors, moving cars and taking things needed to stop and needed to put things back the way they were.”

Mock’s actions allegedly continued after May 28, according to Wright.

“When these charges were originally read to Mr. Mock, he was clearly warned that contacting teachers who were victimized would be viewed as retaliation and should not happen,” Wright was quoted as saying. “However, the minority teacher has been contacted twice asking if she was really scared and whether she wrote a report about the incident.”
