The building I work in has 3 offices with about 2 people in each, and then shared facilities, toilet, kitchen, hallways etc.
The kitchen is next to my office, the toilet is down 2 hallways. I rarely use the kitchen, I have used the microwave once in the past month, I use the toilet maybe twice a week. I walk through the hallways 2 or 3 times a day to get to a storeroom the other side of the building.
The employees in the other offices all seem to know each other, and talk quite regularly. I do not really talk to any of them.
There are no cleaners here so everybody cleans up after themselves.
Over 6 months ago, a person from another office comes up to my office and tells me somebodies left a mess, and as its only the 2 of us here it must be my mess. Even though I was sure that there were on site builders around earlier in the day, but I didn't say anything. Then he ends with, can you make sure to clean up after yourself. Ever since then I have made sure I clean up all the shared facilities, if I walk through the hallway and there's some litter I will be pick it up and not make a fuss about it, if somethings been spilled in the kitchen and I see it I will clean it up.
Over the passed month or so one of the offices has employed 2 part time staff, and more recently there have been maintenance guys onsite. The maintenance people have been contracted here for a long time so again all the other employees know them quite well.
Around 2 or 3 weeks ago I stopped having to go to the store room so as a result stopped using the hallways, walking passed the kitchen, so wouldn't be cleaning up mess that was left.
Now, I get the owner of the offices coming to me saying there's been mess left in the kitchen/hall/toilet and I've been told that you've left mess behind you before. Like I was getting the blame for the mess.
When the reality is the mess has always been there its just I have cleaned it up. Now there's more people on site making more mess, and I'm just not there to clean up after them.
It feels like as all the other employees know each other, they have spoken to each other about it and nobody wanted to say yeah I don't clean up when I'm supposed to, so they came to the conclusion that it was me.
