i know as a teacher we do not have set working hours as such, but I find myself regularly receiving text messages, WhatsApp messages and emails from one particular staff member. These can be at any time of night, early hours of the morning and during the weekends. I got to the point I removed emails coming through to my phone to ensure I got a work life balance but now they seem to be texting and whatsapping about work related things. I am unsure how to approach this with them as they are my DHT. I never reply outside of work but would like to respond in some way to stop future messages coming through. Any suggestions would be much appreciated.
