About 600 human resource professionals converged at Mombasa for the congress, which was organised by the IHRM.
Mr Sitimah warned that more workers might end up losing jobs as some employers cannot afford to pay the recent 18 per cent minimum wage increase announced during Labour Day celebrations.
“Some companies have been hit by low business to an extent that they cannot pay workers. And with the salary increment it will be difficult for struggling firms to meet the labour costs,” he said.
Public Service Commission chairperson Margaret Kobia called on the government and the private sector to allocate adequate funds for training civil servants and workers.
Sponsors of the congress include Nation Media Group, Sanlam, the Kenya Revenue Authority, AON, Higher Education Loans Board, Pwani Life and NIC Bank.
