5 Tips for Gaslighting at Work: Document the dates, times and specifics of the events on a personal phone or laptop. If necessary, notify HR. Know your truth. Don’t be manipulated into doubting yourself and what you know to be true. A great way to check this out is to check in with other people in the office. Always meet the gaslighter with other people present so they can corroborate your version of events. Check-in with yourself about staying in this job. Is the stress worth it? It might seem like the gaslighter wins if you leave, but is this true? Do YOU win if you go? Is that the final boundary around what you will and will not accept? Put as much as possible in writing so there is a paper trail of ideas, meeting changes etc., that cannot later be refuted.
