A 10 for certain (if not even higher) - Just remember, the company's position regarding stress, morale etc. is that there is no connection between either of them and safety. This was said at more than one "commanders" and "future commanders" conference.
I heard it myself when MM (Trng) said that there was "NO" connection between low morale and the possibility of reduced safety due to flight crews being dejected and distracted.
I disagree completely..there is such a connection and if this company isn't careful, they just might see the result of the connection plastered into the ground (or mountain) somewhere....
