Associate and give example which you can relate with the effectiveness of sweeper which proves them as  
Contribuor Sweeper/Non-Contribuor A Sweeper








Performing work activity well
(cleaning perfectly)




Achieving the goal (ensuring the living environment for the locality is clean and hygienic)


Being ethical (doing work honestly; fulfilling one's assigned responsibility)


Demonstrating human concern (caring for welfare of the residents of the locality and for the institution she serves)

I would like to have comment which should be totally personal and in that example you should be there

Thanking you all for nice support
