On LinkedIn, you can send connection requests and develop connections with other members of the network.
By default, all your connections can see your contacts when they visit your profile. If you want to avoid that anybody can see your contacts, then you have to make a little change in your profile's personal privacy settings.
Note: This does not prevent your contacts to see common contacts.
If you are a business owner, making contacts public can be a downside, as your competitors or other recruitment companies will target your employees, customers and partners. You aim to support relationships with all these people for many years, and it is simple to understand that you would not like others to approach them.
