Other people's deleted files end up in my trash can!

Hi there

I am working with a group of people and using the cloud as our server.

When other delete files, they end up in my trash can? We are all very communicative and have a process to make sure no one works on the same file.

Sometimes at the start of the day, my trash can is full of files that I have not worked on. It's very concerning as we don't want to lose or overwrite anything.

Any suggestions about how to fix this? Thank you
