You broke the first rule of twitter, never post anything on your public twitter other than banal corporate hype and safe, non controversial topics you've already seen other worker-drones post. Or, just be uncontroversial enough in your personal life that everything you'd post anyway would never possibly offend the hierarchs now or at any time in the future, like 10+ years down the road.
For most of us, it's just not worth it. The only thing I post on my identity-linked twitter is stuff I'm told to post by my employer. It's just not worth taking this sorts of risks in this environment.
