Are these FA’s leaving because of the flight cuts on specific routs or will NW be cutting/slimming down across the board?

(Can NW cut FA’s from it’s current flight scedual? Please don’t state the obvious and tell me that NW can do what ever they wish. What I am asking is legally, is there a minimum FA ratio per plane configuration?)

The article stated that the FA’s were going because of the reduced schedule.If this is the case and I have no reason to doubt it is, then it makes sense not to have FA’s for flights/routs that NW no longer fly’s. @:-)
