I am often surprised how often email and slack chat volume corresponds to how productive an employee is. I’ve often had employees I’ve had to fire or resigned that after the fact I check their activity and they basically aren’t doing anything.
But using this data without the context is pretty foolish.
And I’ve seen employees that would stun you with how productive they seem based on how much they post in the corporate chat and email, but on actual review did absolutely nothing besides add to the noise?
A lot of corporate chat/email traffic is the very specific technical questions. For those, you can tell if the person is giving good technical advice or generating noise by reading just a dozen messages.
