Well in that case, let's do this - I can send one of my soft skills trainers to your organization. He/she will conduct a 1-2 hours session/workshop to engage the concerned employees. May be this will help. You can tell the concerned employees that they have been nominated for the workshop and this make them feel important. Moreover, this will kind of ease the work pressure and prove as an important learning as well as a fun activity. Mind you, this is just to help you out. There is no cost involved in this.
