The financial crisis has hit a number of outward-oriented enterprises in the Pearl River Delta region first. In the face of the crisis, enterprises have taken measures to reduce costs and ensure cash flow to maintain basic production, hoping to survive the "winter". Labor cost is an important indicator that enterprises can not help but consider. In the past few months, many migrant workers have found that although they still maintain labor relations with enterprises, their wages have been constantly reduced, working hours have greatly decreased, and the Spring Festival holiday has unprecedentedly extended to 1 month... This phenomenon is called "hidden unemployment". The Spring Festival travel season began yesterday. After the Spring Festival, many migrant workers in the tide of people returning home are worried about whether they can go to work again, and some are even wondering "should I come back"?
