Changi Airport's newest ground handler, Aircraft Service International Group, is being investigated by the Ministry of Manpower (MOM), The Straits Times has learnt.
ASIG's former employees have alleged they did not receive overtime pay and were made to work long hours without enough breaks in between.
A spokesman for the ministry said: "MOM received feedback on this case and is looking into the matter."
ASIG, which is already troubled by a shortage of workers, did not respond to queries from the paper. The US-based firm started servicing its first airline customer, Jetstar, a few weeks ago, but a lack of workers has led to major operational glitches.
