Guys calm down!! The reason that memo came with regards to unpaid leave is that the new aircraft are not coming off the factory line in Seattle. There is a strike right now at Boeing and has caused delays in opening new bases and putting more aircraft in existing bases. Because of this the company is trying to save money by first offering unpaid leave and then as he last resort, assigning unpaid leave. Unfortunate but it does say so in your contract since 2002.
