Is it permissible for a Muslim to sell materials owned by the company he works for and keep some of the profit for himself?

I am an employee of Transport company. There were some scrap materials lying at our company and I was asked by my manager to sell them as scrap to anyone. Some persons came to check the materials and offered an amount to purchase. In the light of Islam, is it Halal or Haram to keep and distribute some amount as commission (whatsoever you call it) from the total amount and distribute it between I and to same company's labors who have worked to segregate and load the scrap materials? For example: If the materials were sold for amount 5000, and I kept 1000 from it and distribute it TO the labors and the rest amount I gave to my manager saying that the scrap were sold for amount 4000. **Taking that amount is Halal or Haram for us?**
