Among other things, the staff concerned will be taken care of until 31 March next year for hospitalizations and surgical expenses and, if necessary, for repatriation. This comes after agreements have been reached with the SIA Engineering Company Engineers and Executives Union, the Singapore Airlines Staff Union and the Air Transport Executive Staff Union, according to SIA Engineering. Given the operating loss for the airline and its regional full service arm SilkAir in the first quarter, the monthly variable component of wages will be reduced from August 1 according to the group`s collective agreements with its unions. The benefits are in accordance with the group`s collective agreements with its unions. 4. Current difficult environment The importance of this service increment agreement should be mentioned in particular. The company proposed to apply the same service increment rate for 2013 as the previous year, due to a challenging business environment and strong competition, resulting in significantly lower returns, and persistent high fuel prices. However, their union noted that the joint introduction of our Towards Optimal Productivity (TOP) staff productivity initiative for ground staff has yielded positive results for both the company and employees. Currently, 5 divisions of the company have undergone restructuring and reorganization of employment that have resulted in 23 promotions based on skills for employees and productivity improvements for the company. The Workplace Improvement and Innovation Scheme (WINS) also presented a dozen awards, which were presented in recognition of ideas for improving and improving staff processes. The company, recognizing the efforts of employees to improve their workplace contributions and increase productivity in the ranks, was convinced that there was reason to pay for a relatively higher service increase for 2013.
