@Kaz looks like his boss never heard of read receipts. and acknowledging 300 individual emails every day? even if he took 30 seconds per email, that would kill two and a half hours every day.
@gerrit there are REAL problems with HR. Back in my day, it was called "personnel" or "the personnel department", now you are no longer a person, but a resource. Believe me, that's part of the problem.
