Taking fertile soil from campus for one's personal use

Q: I am studying at a university which has maintained some green areas with fertile soil in the campus for students. Other unmaintained places in the campus have unfertile, dry soil. I have a potted plant in my room and it needed more fertile soil, but I did not know any gardening shop to buy fertile soil from. So I got fertile soil from the maintained green areas and added that to my potted plant.

Is taking this soil from the campus' maintained green areas permissible or is it stealing?

Also, will it be permissible to take the dry soil from unmaintained areas of the campus?

Employer forgetting to pay the employee

Q: I am working as a madressa aapa. The person who employed me is old and sometimes forgets to pay me for up to 3 months. I don't mind, and when he does sometimes he forgets a month etc. Someone told me that he will be held accountable on the Day of Judgement which I don't want as he is old and forgetful and also like a father figure to me. Do I just make duaa and ask Allah not to hold him accountable.
