Here’s a court judgement you should be aware of. It has forced a former employee to give up details of his LinkedIn.com business contacts built up while employed by his former company.
In a previous incarnation I agreed a person could take their contacts with them when they left but not copies of their emails. What any organisation needs is a clear policy. One that sets out the difference between contacts essential for professional development and those which would allow a leaver to set up a business at the employers ‘ competitive’ expensive.
