Well, but as others have pointed out, that depends on the part-time job and the industry. If you don’t work Tuesdays and Thursdays, but those are considered standard hours in your business, clients or other folks outside the office might email you on Tuesday morning with something important, not hear back and not know why — and get irritated. If they get an OOO, they now know what to expect or they have a backup option if the matter is urgent.
Yeah, announcing you were going to delete emails unread and expecting the sender to resend when you return would NEVER fly in my office. I’d get executive complaints about that, especially if it went to a client or outside party – if a client can’t reach you, they will reach out to someone else who may not work at your organization and you lose business. I feel like this delete-it-all philosophy would only work for an entirely internal role where timelines are more relaxed, and even then, I feel it’s a bit unprofessional to foist your own catch-up work onto others, especially if they’ve been backfilling for you while you were OOO.

iOS is offering a feature to set an autoreply for all incoming calls. Instead of merely rejecting the calls, you can send back pre-set messages while you reject it. You have an option to set three quick response message to send back while rejecting the incoming calls.
