I'm having an absolute nightmare. I engaged a specialist firm to help with a large programme of work I'm responsible for. He was part of that engagement. After a few weeks I got reports of behavioural behaviour issues from the stream lead and reported it back into the firm after validating with another team member.
After another few weeks the behaviour hadn't improved so I raised it again with them with a view to coaching and they said immediately we'll pull him out (the engagement is worth a lot to them) and replace him, which effectively lost him his job.
Cue absolute mayhem. He started contacting everybody involved, screenshotting and recording messages. He emailed my boss, his boss and his boss (the COO) saying that I was mismanaging the programme, I was wrong, we were doing it wrong and that I didn't have the experience to do the role.
I got hauled in front of internal investigations to explain and justify myself and my role and behaviour. My boss, his boss and the CEO have all been involved, along with peers at the my bosses boss level to do independent adjudication. The investigation has been going on for several months now.
He pulled a SAR request under GDPR and so they pulled every single communication I made about him via Teams and Email.
So over several months, he's been able to make these allegations against me with impunity and I've had no right to reply. Predictably my org worked on 'what's best for the org'. I'm sure my reputation is irreparably damaged in a firm that I've only been with for 12 months. I took a pay cut with a bonus instead and I'm sure that's now trashed.
I've considered going legal re defamation (the internal investigation found me fit for the role) but he's so batshit (I think narcissism at play) I'm not sure I want to engage any further.
Any ideas? Do I just suck it up and deal with the loss of reputation and remuneration, or fight because these people shouldn't be able to do this with impunity?
