The office is closed today. Colleague has been unwell, though wfh. I line manage them. There's a meeting tomorrow that I will need to cover and get supplies for, meaning I will have to set off much earlier to get these supplies and get the meeting set up, therefore earlierto bed for me tonight. I asked colleague to text me today to let me know if they'd be in tomorrow so I can step in and sort the meeting but they haven't text. Aibu to text them on their day off to check in with them?
