I think that anyone can come here to vent and receive support. The main difference I enjoy here is that this is a flame free atmosphere. This means we are free to disagree with anyone on any type of subject matter as long as your criticism is constructive and polite. It's why I love allnurses.
We have all worked with colleagues that are less than desirable or are less than the acceptable standard and know that any attempt to intervene will lead to personal grief and possible retaliation with passive aggressive/aggressive intimidation tactics (lateral violence) to influence and intimidate the reporter into silence.
I would try to give the students all the support I could. I would, but then again I can never keep my mouth shut, have a "talk" with the director about the concerns I have........ or the things I have noticed and been told to me by the students....and ask for guidance on how to proceed.
I would also remind my students that there will always be those individuals in life that are not what they should be or not that way we would like them to be......that aren't unsafe in practice but they certainly are not the best......but that is life and you need to learn how to negotiate the rough waters.....and make waves when necessary. That this too shall pass.
OP....... I wish you the best.
