This doesn't sound right. In a remote environment it's crucial to be able to find people. You need a good directory/orgchart. In an office you can walk over to section and ask. In a global chat room or such this is harder.

There are directories. I just haven't needed them - but then I'm mostly a dev on some lists of products. There is no global chat room though, but there are optional "ask for help here" lists where all the team leads are likely to be paying attention.

Communication protocols are one of those good things to be sorting out too, from management perspective. I've had this job for a few years now, and am pretty happy.
