I have set up a private board for each of my employees with various subjects such as accomplishments, issues, reviews, etc. It helps me keep track of what each person has done over the course of their employment.
My team uses Slack for general departmental communication. I would like to forward messages in private and public Slack channels to their respective Trello boards when they call in sick or communicate issues to me. Is there a way I can link those boards to Slack without sharing them or making them public to my team?
