Employee Salaries and Reserves do not seem to be working correctly

[Pegasus]

Yesterday, I had the reserves and salaries set such that the Happiness was over 100.00% for all categories and the Attrition Rates was 0.00% for all categories.  I went in and saw that the categories of Executives, Corporate Operations and Cabin Crew all had Attrition Rates of over 0.00%  I changed the Reserve and Salaries for each of those and noticed that the Attrition Rates did not change at all.  Since I did not have a screen capture of the before yet, I did a screen capture of this result and changed the Attrition Rates and Salaries of the above mentioned 3 categories and also changed the salary of the Mechanics and saw that the Mechanics Happiness had gone up as expected and the 3 categories I have mentioned earlier did not have a change to the Attrition Rate and I also noticed that the Happiness factor for those 3 categories is 0.00%.

Note:  I have grossly overinflated values for my salaries and reserves for the categories of Executives, Corporate Operations, Cabin Crew (those that have 0.00% happiness no matter how much I over pay them or how many of them I have in excess of how many are needed) and the Flight Crew (but less out of line in this category since I was using this category because I was changing the reserve and salary values in here just to see if they changed the happiness and attrition rate because this category had a non 0.00% happiness value so I only changed their value once).  There is a reason why I try to keep the attrition rates at 0.00% because with attrition rates of 27.00% and 31.50% I could pretty quickly end up with NO employees in the Executive, Corporate Operations and Cabin Crew.

You need to upgrade your headquarters building. It is too small for the number of employees you have, thus the low happiness. Executives, Corporate Ops and a portion of Customer Service agents are housed in your headquarters.

Manage Airline ==> Infrastructure will show you the usage and capacity of your building. Click (Manage...) and upgrade to a level that has the capacity you need.

I had seen 26/100 usage of the headquarters just before I went to bed last night not sure how it went above 50 overnight when there were no changes made while I was asleep.
