Usually if an employee quits to pursue another exciting opportunity, it is a time of celebration. Not for Mahalo CEO Jason Calacanis. One of his employees sent out a super nice resignation letter. Calacanis' response: "Horribly disappointed in you."

TechCrunch posted the exchange between Calacanis and Evan Culver, an engineer at his search engine company, Mahalo. After the final email, Calacanis disabled Culver's email account. If Culver wasn't dead sure about his decision to leave the company before, he certainly is now. Whatever happened to "Best of luck!" (Read from the bottom up.)

Really?

What is your deal? I will ultimately *have* to come back to Mahalo to pick up my things. Why so rash, what is your rationale? This seems really unprofessional and when other developers and employees see this, it just makes them want to leave ASAP. Is it really that big of a deal that people find better things for them than Mahalo?

Evan,

Don't come back to the office, do not email the team list.

Elliot will send you paperwork tomorrow. Today was your last day.

Good luck being employee 4,367 at a dying company.

Horribly disappointed in you.

Hey guys,

This isn't an easy email to write, but as the subject suggests, this email is to inform you of my resignation from Mahalo effective in 2 weeks. An amazing opportunity came out of nowhere that I just couldn't say no to. I'll be writing code as a UI engineer at and contributing to the open-source project on a full-time basis.

I've never worked with such a great team and learned so much in such a short period of time. I owe all of it to the opportunity you've given me, Jason and I thank you immensely for that. Jeff and Jacob, you guys are amazingly brave for tackling such a great undertaking. I'm impressed you do it with seemingly such ease. Many people would fail quickly in your shoes and I applaud you for your leadership in such a fast-paced environment and against such great odds.

I certainly won't be going far (), so I hope to continue a lasting relationship and hope that we all can work together sometime in the future.

Thanks again,
