We're talking about server-to-server connectivity here.
Huh? The top level comment said something about Google search using SSL and "clicking through certificate warnings" which doesn't sound like server-to-server connectivity to me.
If you're worried about your employer performing man in the middle attacks to read your data, you might be working at the wrong company.
I wouldn't install a company CA certificate on my Mac. It would theoretically allow the company to intercept all my SSL connections. I'd rather validate SSL certs for all the intranet servers manually.
