Do you leave a new job (6 months) for another?

This question came up recently. I think it's good that someone asks, because then it's not too late to consider the pros and cons. And that part of it is really important - that people stop and think about it. That's a workplace skill that will serve you well in itself.

Why would you leave?

You've found your DREAM job? If indeed it is your dream job, in the sense that you went to school and strived to get a job in a certain field (like publishing) and were doing the other jobs until it came around, then you may have a point to look into it. Does there need to be a rush? Will it still exist in a year or two? Is it really as good as you think it is? Is it a "grass is greener" situation? Is it really motivated by salary? Is there really nothing else you can learn where you are?

Why would you stay?

The heading here could also be, why would you wait? The answers are many: You made a commitment. You've gone through six months of learning curve. You may be in line for other assignments. You may be on probation all over again if you leave. You are probably just getting into deeper work, developing relationships. Added to that, you may have just figured out how the phones work and where a good place to grab lunch is. Unless the workplace is operating like a train reck, consider the reputation, size and opportunities at the existing company - are they things that you value as much or more than at your supposed dream job somewhere new?

More reasons to think about...
Although job hopping is more acceptable in today's economy, you likely won't find satisfacation unless you dig your heals into one place for atleast 18 months. People and processes may make you want to head for the door some days. That's probably the case for many people and a good way around that is to find what makes you most happy at work and outside of work and focus on that as much as possible.
