I work in a manufacturing company in UAE as HR Incharge and have been getting regular complaints about the mess done by the staff after eating lunch in the office pantry like dropping food, leaving used food containers on table, spilling food in the fridge etc. I have put up warning posts on the pantry walls and also sent emails to the staff about the guidelines on the DO and DON'Ts of using the common lunch area. But still, the problem continues. Can anybody share any tips/solutions that have worked for you?
