Hi Shilpa,
Seems you are much overloaded with work pressure.. or environment.
See.. they are the persons who try to disturb the working environment. Moreover, its HR who is been most hated in the organisation.. Most of the cllegues or top level persons of other department just hate HR persons..
But yes even you are the best friend of their junior level employees..
Its our responsibilities to handle the situation calmly.. But if somebody is trying to pull the legs, be confident and do reply the things.. If you remain silent for 1st time means don't answer them then they will start creating problems. so better solve the problem when it comes for 1st time..
To remember the things.. do one thing, try to note down the work for that day in a note book.. it helps to improve your efficiency of work...
Its not your loss of memory or other things but its because of over loaded with work pressure. be relax.. confident and enjoy the work don't take tension of works..
Hope you will manage the things..
Regards,
Amit Seth.
