Say for example you've been given notice on your part-time job, due to poor performance caused by stress and anxiety from a coworker hounding you. This has been raised numerous tines, and ignored, by employer ego has sided with the colleague (but you're over it and glad to be moving on to something else.)
Then say your coworker has WhatsApped you tonight at 10pm asking if you've gone x,y and z on this day... and it's not a work day, then gets antsy you've not replied... you're not being unreasonable right??
I'm sat here trying not to have an anxiety attack even though I'm totally within my rights to ignore them.
