It is very important to have this within your facility. One person can bring negativity to quite a few people. Some of these students listen because in some cases, this is their norm. They are used to it and listen and believe it. To turn the negativity around will take effort from the whole staff.

Have a big smile on your face, make them feel welcome and that you are here for them, and explain any future possible obstacles in the future that you are available for them for anything

I think with any situation, you have to have boundaries. I have noticed with some of my students this is the first time for this. I always tell them that even though they are in school, the professionalism starts here.
