The best morale boosters are ones that understand how humans work and think. Incentives are a good way to start; a bonus for achieving a milestone ( such as working a certain number of hours without receiving a complaint ) is something that will make a worker feel special, as well as let them know that their boss is looking after them directly.

Recognition is another important form of morale boosting that is frequently overlooked by call center administrators. Human nature is such that even a simple thank you can last a long time. Call center staff that have been working the phones a long time develop a confirmation bias that magnifies one type of call and diminishes another in their memory. If their bias is toward positive phone calls, then half the battle if done. If however it turns out to be toward negative phone calls, they will need help to keep their morale high.
