My colleague was late today due to some minor train fault on NEL. She messaged our manager out of courtesy but look at how rudely our manager replied. This is getting too much. She has been here for only half a year, while my colleague has been here for almost 4 years. Under her new "leadership", two staff had already resigned. She is a 41 years old unmarried woman. She is the type who misspells people name in email, as well as reading whatsapp messages but not replying to it.
