When announcing resignation, is it unprofessional for me to ask my boss if it would cause an inconvenience for me to work only another 5 to 8 days instead of a full two weeks? I am able to work for two more full weeks if my boss deems it helpful to the team or necessary for out-processing. However, it would be useful to me personally to be able to move more quickly to my new job.
I do not think there will be a need for me to perform a lengthy hand-off, since my skillset in my current job is not so much an in-depth knowledge of the product (I have only worked on my current team for four months) but an acuity for software design and knowledge of C++. I also suspect that the out-processing will leave me with very little to do my last several days of work if I stay a full two weeks. I have vacation time I could use to fill in final days if this caused any sort of legal hassle with the contract, provided my boss didn't have a problem with it.
The importance of not committing a faux pas here lies not only in not burning bridges with my current boss but with not giving the wrong impression to the company that is hiring me.
