@cherrypavlova - MY tone is unpleasant?! Compared to those respondents who've outright admitted they're prejudiced and even acting illegally?! 
You made that comment in the context of mental illness. I took it that you were referring to people with a mh DX or with a mh condition that wasn't DX because why would you need to be talking about otherwise unreliable employees on a thread discussing mh discrimination in employment?
Rabbity - classic case of needing to rtft - the op is NOT a discriminator themselves, instead they believe they are the victim of discriminatory practice and are frustrated as a result. Yes there are some pretty disgusting posts on here which I'm not even bothering reporting for 2 reasons
1 the people making them deserve to have their prejudices at least known on mn
2 mnhq aren't in my experience particularly good at dealing with disablist posts when it comes to those discriminating against the mentally ill.
There are numerous posts on completely unrelated threads where posters have put the most appalling even criminal behaviour down to someone possibly being mentally ill with no evidence of this.
There are also lots of posts where specific mh conditions (I'll admit I tend to notice the ocd ones) are spoken of in dismissive, even "humorous" ways - eg "I'm so OCD I have to have all my crockery matching" "I'm a bit OCD" etc
There is still SO much ignorance, miseducation and prejudice to address and those of us most affected by it are generally the least able to deal with it because we're already knackered just from dealing with being ill! From trying to get the help we're eligible for despite institutionalised prejudice causing many obstacles to treatment, money to live on, support for our loved ones...
We need open and honest discussion so that we can correct the misconceptions and educate people as to our reality.
