I returned to work in September on a part time 3 day basis. It's local government office work dealing with run of the mill stuff so no urgent life and death stuff. Either the culture has changed since I've been away or I have, but a manager thinks it's ok to use what's app to message staff about work matters at weekends. I've noticed other colleagues sending e-mails over weekend. I object to being contacted and I object to the acceptance of people working beyond their contracted hours. It creates unnecessary pressure (on me!) to try and keep up. I'm tempted to raise it in team meeting, will I look like a workshy stickybeak?!
