Whilst I would also agree that terms and conditions in some airlines and particularly how air-crew are perceived by the bean-counters at the top could all be items worth discussing - I can't help but read into this a bit of 'jumping on the band-wagon' by citing the German Wings accident.
The results of any official investigation into this accident are weeks/months away and while there does seem to be some evidence to indicate human factors - I really feel that the prosecutor, press and industry have been extremely quick to condemn this First Officer.
Whatever the cause of this accident a full and thorough inquiry should find out the causes and reasons behind this dreadful episode - however I can't help but feel that to link what type of hotel crew stay in, whether they pay for their uniform etc with this crash is a little far-fetched.
