Singapore Prime Minister Lee Hsien Loong said on Friday that Singapore can look forward a 'good year' this year, with the country emerging from the financial storm in a strong position. Lee said in his May Day message that Singaporeans should take the opportunity to push forward with improving productivity and transforming the economy, local TV broadcaster Channel NewsAsia reported. Singapore's economy is expected to grow 7-9 percent this year, with a blowout first quarter of 13 percent growth year-on-year. But Lee cautioned Singaporeans to see the remarkable performance in perspective. He said some sectors like electronics and biomedical sciences expanded sharply but others had not done quite as well. He noted that while firms push on with the productivity effort, workers need to improve and achieve greater mastery at their jobs. During the downturn last year, workers here had taken the opportunity to upgrade their skills. Lee said this momentum must continue even as the economy has improved. He also urged companies to work with unions to build up variable bonuses, and structure their wage systems to be more flexible over the longer term.
