I've been working for a telecom company in Brazil. It was bought buy another giant telecom company and merger has caused a big problem. The headquarters is in São Paulo but the rest of company in Curitiba and I felt bad with your conditions. A solution was show service. Some workers were fired but people who weren't fired did excellent work. Integrate the systems and show that your process is better than the headquarters. People continue to be upset, but now, things will be different.
