Greenville is non-union. GE has been trying to escape unions for years by shutting union plants down and moving the jobs to Greenville.
Greenville has been fortunate in that respect. However, Greenville quality is declining due to elimination of seasoned GE employees and hiring contractors for manufacturing jobs (no commitment).
Also, leadership is constantly changing so there is no consistency and/or loyalty. Employees are constantly training the revolving leadership. As the Greenville quality declines the cost is increasing.
Declining gas turbine sales, declining stock prices, declining investor confidence (due to a current major problems with a power product), declining quality, and increasing cost will lead to layoffs in Greenville. GE is good at playing the shell game with money.
But they are running out of shells. Investors are wise enough to read between the lines. And so are some customers.
