How much is public vs. private

I've been debating with myself about posting a work-related topic, but every time I re-read my draft, I edit it a little and then hit the save now button instead of the publish post button. Why? It's just too sensitive. I wrote a long post about what's been going on in my work life lately (lots of churn and change and uncertainty) and it's too nerve-wracking to publish. If someone at work finds it, it's possible it would have repurcussions for my career. Negative ones, I might add. And so I wrestle with my feelings and opinions in private because I cannot write about it 'in public' on my blog. What's unfolding at work has caused me sleepless nights and chewed up nails. I am happy and grateful I have a job, but what's been going on really bugs me and I want to scream through the written word, but instead I just save it. Edit. Save it again. And so what is happening to me in public at work has to remain private. Or my feelings about it need to stay private, saved in draft form to never see the light of publication. It's a shame because my opinions are strong ones on this topic and I cannot voice them. Unless I want to lose my job and then that would begin a fully new post that a future employer might not appreciate. I'll just keep my thoughts to myself but it leads me to wonder. Just how much can be stated without fear of repurcussion> and does that mean we really have lost our freedom of speech. Food for thought....
