Laws governing teleworking are complex and incomplete. In many areas, a teleworker has the same rights, under the same legislation, as an office-based worker. A European voluntary agreement on teleworking has been developed (from which much of workSMART's guidance is taken), but this is currently not enforceable in law, and has not been implemented in the UK. Instead it currently acts mainly as a good practice guide for employers and employees.
If you are considering teleworking, it would be a good idea to talk with your trade union representative (if you are a member of a union) or to seek individual legal advice based on your company's proposed teleworking agreement.
