Being in safety and security, the co-worker blamed me for lack of police response when she pushed the panic button even though I did not maintain her panic buttons – somebody else did. She called me after the incident and demanded action. Incredibly, the college responded within 3 days she had a new panic button. Unfortunately facilities department put her new panic button in her office without consulting her – prompting her to go a crusade for my job.
About a year and half went by and this co-worker was apparently weekends playing cards with my boss – an individual high in the college bureaucracy. They both live in the same neighborhood. She was able to bad mouth me enough that she got me put on probation. Unfortunately I successfully refuted all of the negative charges against me and kept my job. We still work together to this day.
