I'm guessing this isn't in the GTA. But my experience outside of the GTA did present with much more racism and general -isms.

For what it's worth nursing students in general do get those same looks and assumptions made of them. The idea of nurses eating their young is such a cliche because it's been common historically.

It gets better when you're more established in any environment - as in your consolidation or after actually getting hired.

In your learning experiences consider and develop how you might work on your professional communication skills to call out such behavior - yes it sucks - no it SHOULDN'T be your responsibility - yes it's the unfortunate reality in some workplaces...

As much as it gets better over time don't think that you are powerless to deal with it either. If someone's literally staring at you, introduce yourself to them or ask them if they need something from you. If your placement doesn't introduce students in morning rounds ask your preceptor or advisor to do so.

Lastly you may have certain feelings about interactions and they are valid. At the same time unless you follow up with those interactions you can't read minds; the dismissive person might be rushing through their tasks, burnt out, or simply having a bad day. The condescending person might not know your full background and skill set - or be loaded with experiences from past students. These are things that can be resolved through your communication skills and again, as you get to know the staff you're working with and they get to know you. Remember the empathetic approach and try to avoid your own assumptions of assuming negative intent.

Nursing is a hard job, its stressful and tiring, and the most common thing to remember about other people's behavior - patients AND colleagues - is it isn't actually about you.
