I worked in the construction site of No.2 Team of No.14 Metallurgical Plant in Xundian Pioneer Chemical Plant, and I didn't get paid for four months. What should I do?

Which province is the chemical plant mentioned by the questioner? Under normal circumstances, wages can't be paid at the construction site, so you should ask the contractor for it. But the nature of your project may be different, but you can report the situation to the local labor department. It's best to call a few people together, which will be effective, especially when the year is approaching.
