No idea about your specific legal situation, as it heavily depends on where on earth you are.

But what sprang immediately to my mind is that it sounds highly illegal if the manager is indeed right. They knowingly let you do things, which apparently they know you are not allowed to do. In a health care environment, which normally have some kind of control instances.

So regarding the “benefiting you”: have a talk with your old manager about somebody telling the control instances of your profession. Orrrr maybe they could help making the transition easier for you… For example by paying the training for you.

I’m playing Team Fortress 2 since 2010 and have around 2500 hours. So it’s not hard to reach high numbers if the game is old enough, which some are.

That does not seem to be what research shows, but rather your personal experience:

For animated children movies, I found that 80 % male leads are reported for 1990-2020. Source

Couldn’t find data for children movies in general.

And I found for children books that there is still a slight male overrepresentation on average but in general it being around 50 %for the last few years. Source, search for “Fig. 2”

Yes, it’s not a counter point but rather an also important parallel discussion. We need to have higher standards for male role models, or we will continue to have incels fill the space.
