There’s a sociopath colleague or boss at the office? You better start taking notes with Agenda.
In a nutshell:
Start keeping a diary of what the sociopath says and does, noting dates, times, people involved etc. This is very important especially if things go on for any length of time because it’s often very difficult to keep track of all these things when a sociopath is causing drama and chaos. Having a written record often proves invaluable.
