I have just called them again and told them that they are people willing to contribute to help with repairs. But it is no help: decision from management is final - profit is so small that is does not pay off to do anything, and plus is that they are on rented place - one extra problem.
If workers are the owners - then maybe this could work, but I am afraid that management decision is final. Worker with who I spoke have said to me to thank you all for your thoughts and willingness to help - but is it over .
Sorry to bring bad news (again).
