About this question
I have viewed Gmail's certificate chain at my workplace, and I realised it's different. It looks like this:
Root CA Operative CA1___________.net mail.google.com
When I get the certificate chain at home, it looks like this:
GeoTrust Global CA Google Internet Authority G2 *.google.com
Obviously these certificates are issued by my company. I recently read some other thread on security.stackexchange, and they said the company is eavesdropping (using an MITM proxy) the HTTPS communications to protect the internal network and the client machine against viruses. That means they can read all of the encrypted package that has been sent via HTTPS, including this message too.
If this is true, can I work around this?
