We've been working on a social media policy for a client. As a point of reference, we took a look at a precedent on a popular legal information service. This suggests the following:
You are not permitted to add business contacts made during the course of your employment to personal social networking accounts, such as Facebook accounts or LinkedIn accounts.
OR
The contact details of business contacts made during the course of your employment are regarded as our confidential information, and as such you will be required to delete all such details from your personal social networking accounts, such as Facebook accounts or LinkedIn accounts, on termination of employment.
I understand why these have been included. Lists of contacts (and more particularly customers) are valuable to businesses and typically protected in employment contracts through confidentiality provisions and restrictive covenants. The advent of social networking sites has meant that businesses have lost control of this information (because it is held by employees within their personal accounts). These clauses are intended to limit the risk - but I just can't see them working.
The clauses suppose that lists of contacts are still the company's information ("our confidential information"). But most LinkedIn users can now see each others' lists of contacts - are they really "confidential"? I can see the first option (no use of LinkedIn) working - but for most businesses I'd have thought that the adverse effect on business development of a blanket ban on business social networking would outweight the benefit of retaining control of the customer list.
My feeling is that businesses will need to rely on restrictions over what ex-employees do with information rather than which information they are entitled to have. Claiming "ownership" over someone's list of contacts is rather outmoded and out of keeping with social media norms. For example, a company could hardly require staff to hand over all their LinkedIn contacts when leaving - apart from anything, this would probably breach the Data Protection Act (you link to the individual, not the company). So you can keep the list - but you can't sell competing products to them.
This made me wonder whether the notion of customer lists being protectable trade secrets is sustainable in the era of social media. Will it seem quaint or Big Brotherish in the future that companies tried to "own" the social capital created by their employees?
