It is crucial to keep your staff happy. If your management and/or your crew is not kept happy you risk it will impact the cargo load on each departure. Rule of thumb is that the more unhappy they are the less cargo load you will have.
If morale goes below 50% the cargo load is impacted quite a lot as well as the staff perks for the unhappy crew and management members will lose part of its effect.
Your staff has a “fair wage” in mind always, which is based on your company value. The greater and more successful your company is the more they will ask for.
If their current wage is below the fair wage their morale will drop gradually. If they are paid more than the fair wage their morale will increase.
The further their current wage is from the fair wage the more the morale is impacted on a daily basis.
A raise will per default give a 3% morale boost while a paycut will cause a 7% morale drop.
Tip: You can train some of your staff to give a lot of benefits towards both keeping morale up as well as your negotiation power over the crew.
SPECIAL NOTE! The release of the new staff system was made so everyone started with wages as they were new users to the game. Established users will have a very high company value meaning the “fair wage” the staff expects is a lot higher than where it starts off. So you will need to give a lot of raises before your staff feel they are getting a fair wage.
See this as a benefit, as you will save a lot of wages in the period until the reach the fair wage. If we started all on a fair wage, you would pay a lot more in daily salaries, but not be needing to give raises. Now you get the flexibility to build and learn though it requires a lot of raises to begin with.
