FWD: Cutting a contract short

[Administrator]

Forwarded anonymously on request:

I'm currently in the middle of a 6-month contract that I'm considering 
cutting short to look for another opportunity. There are several factors 
involved, such as a relatively low current pay scale, the fact that my 
current position involves very little writing (maybe a few days worth 
out of the whole 6 months and that's pretty much done), and that the 
contract is expected to end shortly before Christmas, a rough time to be 
out beating the streets for a new contract. I'll mention that I was told 
up front there is a fair chance my contract might be extended, but 
there's certainly no guarantee of that and even then most of the 
negatives I mentioned will still hold true.

I'm concerned over how many and how badly I'll burn bridges if I do 
leave. There's the agency I'm working through. I haven't worked with 
them before, but I'm fairly new to this area and am worried about 
burning relationships. And of course I'll annoy the company I'm 
currently working with since they have another non-writing task that 
they'd like to stick with for the next few months while they prepare to 
roll out a product.

Can anyone offer any wise words of counsel?
