I work in a senior NHS role, within a very specialised small team. I joined a single colleague in this role some time ago. I was aggressively recruited. Moving jobs is not an option.
My colleague is widely acknowledged to be “difficult”. Long story short this colleague refuses to discuss annual leave, refuses to cross cover, accuses me of hogging the department resources, triangulates, does not reply to emails for months and sends incomprehensible replies when he does. In meetings alternates between accusing me of bullying (subtly rather than overtly) and claiming I have said things which I am certain I have not. Mediation failed as it was just hours of assassinating my character rather than discussing any actual workplace issues.
Management are morally supportive but not being proactive and basically insist that I must continue to work with him, where he has been consistently unwilling to work with me. I am extremely overworked and fear I am rapidly becoming burnt out.
I have had some coaching sessions who have advised me to use a grey rock technique- which I am working on but there needs to be some communication within such a small department for any progress to be made. I’m looking for tips on how to manage to be a grey rock within a professional setting?
