Hi Mary Lou,
In my personal opinion, I think you should keep your business endeavors to yourself until you're more established and could handle losing your full-time job if your employers get upset. Hopefully that won't happen, but it may be best to play it safe.
I know how frustrating it can be to be so excited about your new business but have to keep it quiet; there are only 25 people in my office, so we're a pretty tight-knit group. It's so tough not to tell them all about my new venture, but I just can't risk losing my full-time income right now. I work for an ad agency and would love to utilize the expertise of the graphic artists, marketing gurus, and
PR professionals that I work with on a daily basis, but I would also feel bad asking them to keep my secret from the higher-ups until I'm ready to quit my J O B.
Good luck to you!
