I'm currently off work with work related stress, largely due to bullying at work which my LM and their LM has passively allowed and done nothing to help rectify.
Can anyone advise on privacy and confidentiality.
I strongly suspect my line manager is disclosing my issues, details of what I believed were private phone calls between her and myself as well as my occupational health questionnaire with the team manager who manages the team I worked in?
Usually we keep in touch via text/email or mobile calls but today she stated she was going to phone me via her laptop using Skype. During the conversation it was clear she was pressing the mute button while I was speaking. She was speaking without pressing it off again resulting in broken conversation. I said the line was bad...her response was to say 'you're not on loudspeaker'. 
It was only afterwards I considered she was maybe using a 'squat box' so someone else could be there and hear what I was saying and possibly coach her on what to say.
If she had another person in the room while I was talking about my mental health and fears of returning to work with the bully's all while this person was listening without my consent has she done anything wrong or is this type of underhanded behaviour ok in line management 
She knows I have major issues with the lack of privacy and confidentiality in there and I've told her that I want anything I discuss with her about my issues to be treated in strict confidence between myself, her & HR, which she agreed.
It feels like I'm being completely set u, I'm so angry I want to confront her but I know she'll deny it and make be sound like a loon.
Any advice?
