A celebrity tutor was taken to court by his former employer for allegedly breaching his contract by joining a competing tutorial school last month, according to a High Court writ. Weslie Siao Chi-yung, also known as Siu Yuen, was sued by Charlotte Leung Yuk-lin representing King's Glory Educational Centre and four companies related to the school. King's Glory claimed Siao had breached their agreement by joining Modern Education (Hong Kong) Limited and asked for a court injunction to stop Siao teaching at the new school. But Siao reacted swiftly by filing his own lawsuit yesterday claiming King's Glory misled students to believe Siao would still be teaching them this summer. The writ says Siao was a well-known Chinese-language tutor among secondary students and parents. He started teaching at King's Glory in 2005. King's Glory claimed Siao and his firm Hentix Limited reached an agreement in July 2011 in which he promised to teach at the school until next year. If either side wanted to terminate the contract, they were bound to providing at least one year's notice, King's Glory said. Siao was said to be prohibited from providing tutorial services to similar educational institutions within one year of the expiry or termination of the agreement. He also could not solicit or entice King's Glory students or teachers to leave the school. Siao allegedly told King's Glory, through his lawyer, of his wish to terminate the contract on May 28 this year, and joined Modern Education thereafter. King's Glory asked the court to declare that the agreement between them and Siao was still valid and award damages. But Siao claimed King's Glory had undergone a change of shareholders in April and come under new management, and that after learning of the changes he had no intention to teach at the school and informed the centre he was leaving in May. However, he found King's Glory published adverts showing he would teach their summer courses this year, and said the centre had misled the public and harmed his reputation. Siao was seeking damages from King's Glory for malicious falsehood and asked for an injunction to stop the centre passing off any tutorial classes in his name.
