The equal opportunities watchdog is looking into complaints that the MTR Corporation discriminated against a worker suffering from depression. The worker, identified only as Ms Chan, says her performance was rated below standard and she was assigned to jobs she was not accustomed to, aggravating her illness, as she feared she would lose her job. Legislator Pan Pey-chyou, who accompanied Chan to the offices of the Equal Opportunities Commission yesterday, said that although she told management about her illness, the railway operator did not deal with it properly. Instead, she was given warning letters and was told she might be sacked if her performance did not improve by the end of this month. 'MTR, as a company that provides Hong Kong's most important transport network, with about 10,000 employees, should take the lead in shouldering social responsibility and prevent its workers from being discriminated against and harassed,' Pan said. Chan, who has worked for the MTR for 18 years, developed depression in 2005 and recovered after treatment, but she suffered a recurrence last year. Pan said the commission promised to look into the case, as it was covered by the Disability Discrimination Ordinance. The MTR Corp said last night it would not reveal information or comment on the performance of individual workers. 'But our company always abides by the law,' a spokesman said. 'We have a well established system in assessing working performance, and we will help workers whose performance was regarded as not good enough by offering them retraining.' He said workers could speak to management if they had any demands.
