It sounds like the issue is really one of company policy, so it's best if you wait for the manual from your firm.
I know as far as my workplace goes, I'm not allowed in theory to do any freelancing without permission of my employer, especially if it's potentially conflicting with our main line of business. In practice, as long as it doesn't interfere with my job and doesn't detract from business opportunities or cause other problems, they let it slide. (A good example is that I've been working a bit of software I wrote for my wedding into a workable product. I might start charging for use of it, but my company's pretty understanding about my doing things with regards to it, so long as it's not during workhours and doesn't keep me from working 100% when I'm at the office.)
But you should
check to see what the specifics are when it comes to your employer or you may find yourself out of a job.
And that would be a Bad Thing.
