The DTI has just published the booklet: Managing Change - Practical Ways to reduce long hours and reform working practices. This is a joint project between the TUC, CBI and DTI.
The booklet identifies practical ways of implementing change management programmes in the workplace and share this learning between businesses.
It is very much aimed at HR practitioners rather than lawyers. But there is a case study of working practices at Eversheds (where flexible working seems to be huge success) - see p20.
