This is true! The nuclear option also helps the recently returned vacationer understand what is a priority and what isn’t. But, as boyd wrote, “if you just turn off your email with no warning, you're bound to piss off your friends, family, colleagues, and clients.” The blog post offers some helpful steps to make a clean break feasible — they include communicating with colleagues about the sabbatical long in advance, managing expectations of those who rely on you, creating a backdoor for true emergencies, and then, right before going away, reminding everyone about the sabbatical once again.
Start by recognizing your backup contacts for the time when you are out of the office. Make sure that, when needed, they can be available to help customers instead of you. Meeting with your co-workers and making everything clear should be one of your top priorities. The person who covers you while you are gone should not find that out by receiving an email out of nowhere. Be professional and plan everything properly — you are about to take a break, after all.

Careful. Holiday revelry and debauchery ahead. Proceed with caution (if you dare).
Sometimes people will think it’s okay to ask a quick question while you’re out of the office. Avoid the interruption by including at least one person who can answer questions in your absence.
