In a few weeks I'll be starting a three-month long sabbatical from my work at Automattic.
As a benefit provided by the company, it's pretty amazing. After every five years of employment, Automatticians are eligible to take a two or three month paid sabbatical to have a break from work, refresh and recharge. Several people (mostly used to academic versions of sabbatical) have understandably asked what expectations are placed on us during that time: research, writing, professional development? Nope, it's all about having a break.
For me personally it's a really neat opportunity, and one I haven't had before in this particular way. I started my first company when I was 19 and have pretty much been working full time ever since. Automattic has a generous and flexible time off policy but to have such a significant amount of time to pursue hobbies, personal projects and time with family and friends is really quite an amazing gift.
