Cashflow Management
I agree with most of the opinions about why this Pay review has not been announced so far.
But there might also be a problem of Cashflow Management.
With the May salary, all EK employees will receive the "Bonus 2014".
This takes a lot of cash wich has to be paid out within one day. Even for EK, May is the most expansive month considering salaries every year. Unless there is no Bonus.
To reduce this Cash Amount AS is not allowed inform about the Pay Review for Pilots until the May salary is paid. AS will do it after the 25th and it will be back paid for the month of May in the month of June.
Just my 5 cent worth of an opinion.
