Very long back-story, will try to sum up:
Employed by organisation (1) located at organisation (2), used to be employed by (2) at same location, with same LM. Been in higher position, new organisation just under 2 years.
Covering old and new position for 13 months before my replacement started end Oct '17.
LM at (2) causing issues for long time, recorded these and reported to LM at (1) who with HR Consultant recommended mediation, following our meeting, Couldn't face as very depressed/stressed/anxious and ended up off sick for 7 weeks at beginning of year.
Mediation never resumed.
Went back mid-March. New colleague has been awful with me, sharp, snappy etc. Just kelt relationship with LM professional.
Very little support from LM at (1) and no contact since end of June.
Made Subject Access Request and got it back today.
Very unhappy with tone of emails about me from LM at (2) to LM at (1) didn't say anything to LM, but left work just before lunch today and another colleague let LM know I'd gone home poorly.
What is best way forward, I think today's emails confirm that I should leave? Do I go sick until 2 year point (mid-Oct) as I might want to put in case for unfair/constructive dismissal? Or do I just resign?
Thank you 🙏
