I’m on mat leave, due to go back end of Aug. I went in for a KIT day on Wednesday. My line manager has since set up a WhatsApp group between me and my mat cover and her and messaged me on it about finding dates to meet to discuss next step and how to use my KIT days. AIBU to expect her to message me by work email and not my personal phone? When at work we did WhatsApp and I’ve never really been precious about being contacted outside of work hours etc, but this feels different? It feels like work is now hanging over my head 😞
