Pros
You will do well if you are younger with little experience. Those who have grown with the company are firmly planted as a skeleton team. You can move up ranks certainly, but you'll hit the ceiling and then all there is is moving around horizontally somewhere in the WRHA.
Cons
I had a rough experience after disclosing an invisible and harmless disability, one which I needed support. For me it's very internal but I shared it because I thought it could be helpful to the WRHA and myself. Everything went fine up until that exact day. Then it was a disaster. 1.5 years of micromanagement, harassment, I was bullied with very mean comments from management. Strangely the rest of the entire office still liked me and so I felt like there were two worlds: one where I got along with my peers reasonably, being slightly older. I would sit in the lunchroom, play games, listen to their chatter, I was invited to go on walks in the skywalk, coffees etc. But when management got hold, and it began to leak, they backed away a little, and I was watched like a child and treated as if I were not trustworthy by management. Although my morale for my actual job never went down, my managers didn't look at my work which I was so proud of. Instead they nitpicked on my protected traits, but not my actual faults, just I suppose the "label" of my disability. This watching me flip-flopped from a letter giving me the usual job expectations, and policies to filling in the blanks to try to make me look bad. At the end it was flip-flopped to a PIP review where, I could not speak, they used their authority to silence me, and they put spins on my words, lies and false accusations to HR. There never were any formal complaints about me. It was all just these meetings where I knew for sure what they told me about me was completely fabricated. They never offered accommodation, I asked twice and I was put through hoops. Instead I was driven right out the door, or I should say bullied. It's left me with damage to my reputation, damage to my confidence that I can work somewhere without someone targeting me, and damage in that I'm unemployed. I'm not wallowing in pity, but I was a very good worker, and I feel that my competence may have been a factor, in that, there is always jealousy towards me wherever I go, yet I usually am rewarded by management. I do not believe their accusations of me and they do not define me, my resume proves I'm very good at this. However, just the feeling of being targeted is sad. I suggest, don't be too good, and really get along with the managers and the whole office “click” to survive. If you do that, you will never know about this dark side. The moment you are different, you are treated like a cancer. And it's sad because this is the health industry. You'd expect a higher standard.
