You feel they are bored, but they may not really be bored. As part of breaking the supposed boredom, take them to a workshop outside the workplace to find out the real situation. By doing so, they may come out with the reasons for being bored. Meanwhile, if they are bored because the work is now monotonous, it means they are doing the same thing over the years. The solution is to find them different things to do. For example, if they are mainly engaged in designing websites, you can let them go into designing new software for capturing staff data or software that takes information not through typing but through writing or talking to the computer for the computer to record the information in written texts. The task may be a difficult one, but it would certainly put them on a different pedestal.
