Keep in mind that it is usually not a good idea to sync personal data between work and home as it is best to keep that separated and might be required in your corporation for safety.

Normally only sites you visit on your laptop would be visible to others that share the same internet connection like in a corporate situation. If you use Sync then your employer would have to inspect your device (laptop) to see more detail also because you normally visit a website via a secure connection assuming that your employer isn't using an open proxy to connect to internet (not tunneling like via a VPN).
