A campaign aimed at challenging attitudes to mental health problems in the workplace has been launched.
There are concerns about harassment at work
Figures from the charity 'see me', suggest that one person in four is likely to suffer a mental health problem.
And more than a third of them will be bullied or harassed by their bosses or colleagues at work, it is claimed.
The campaign is designed to overcome prejudice and aims to change attitudes by persuasion, rather than the law.
Experts allege patients are facing a much greater stigma than previously thought.
They claim a large amount of talent has been wasted because people with mental health problems have been too afraid to reveal them during job applications or interviews, or when going for promotion, for fear of how other people at work might react.
As well as running a series of adverts, campaigners also have the support of employers' organisations who believe most companies will want to keep the staff in whom they have invested.
Health watchdogs last month warned that people with schizophrenia were being let down by a patchy network of care and poor record-keeping.
A three-year inquiry into services for people with mental illness across Scotland found "far too much variation" in the standard of care.
The NHS Quality Improvement Scotland (QIS) review found some progress since an earlier performance report in 2002.
There are 12,000 people in contact with services, according to the review team.
However, the report said: "No NHS organisation has a system to record all those with a diagnosis of schizophrenia and the actual number of people with the condition is likely to be higher than this figure."
Health Minister Malcolm Chisholm pledged extra funds to support an existing
mental health information programme, but said boards were accountable for their
performance in delivering services.
Schizophrenia is a disabling mental illness where disordered thinking disturbs an individual's ability to function normally in society.
Symptoms can include delusions, hallucinations and catatonic movements.
