Thanks very much for bringing this up! I haven't even looked at using the Employee Center because we use the Service Portal for everything. If it's going to be deprecated, we're going to need a fair amount of notice. As you noted, all of our customers are internal, though not all are employees.

We've looked at using ServiceNow for some HR things in the past but we set it aside then and haven't picked it up since. So I have no ideas on how we'd keep that separate from other internal requests or access in general.
