With that update - no more messing about!
You need to speak to hr ASAP!
Someone with her attitude to other people's money should absolutely NOT have any financial responsibilities.
I was involved in a charity and friendly with everyone but especially the treasurer and her family (or so I thought)
As a result of getting to know them and spending time with their extended family too certain things about their expenditure seemed suss.
As my suspicions grew I made the mistake of making comments but not handling it properly assertively (I have mental illness and wasn't very well at the time)
The next thing I knew I was being gaslit on certain matters and THEN I was accused of making a play for her husband! By them both! Completely and utterly untrue had never even been alone with him and tbh while he seemed a nice enough chap not my type.
I was ostracised from the group and the whole thing was extremely upsetting.
About 8 months later I bumped into the chairman in the supermarket, I'll be honest I clocked him and turned to avoid. He came sort of jogging up to me and I got an apology and an invite to return to the group - the treasurer had been caught embezzling the funds and using the charity to get payday loans etc!
I didn't return as I had no faith in them after how they had treated me.
Awful time. I'm not so trusting now.
