Chandler, who works for Truck Inc, is in charge of developing a new certification program for Truck Inc’s drivers. Chandler will be working with a small team of 4 employees, and details of the program must be kept private from the drivers. They are currently using a group direct message to plan the certification program, but some people on the team will be going on vacation soon, and new members will be replacing them.

What should Chandler do next?
