Outdoor jobs: What the workers say

After the red alert was issued yesterday, the company issued us breathing masks and protective cream. But the working hours haven't changed much. We still have to work from 7 am to 9 pm.

We did receive breathing masks and a warning text message from the company, but since we are doing promotion for our products, there is no way we can sell things to people with this mask on.
