When employees are suffering from the effects of stress they can become lethargic, have low concentration and limited communication skills. This in itself affects performance at work as the employees can become underproductive and isolated as they communicate less and suffer under the burden of being overwhelmed. Low concentration affects staff morale as they begin to feel useless or unworthy of being given tasks or projects. Both of these effects contribute to employees becoming lethargic as they become complacent and begin to not bother making the effort.When people are stressed, they can not consider a point effectively and they decide in hurry and make mistakes in their jobs.
