The four times that I can think of off the top of my head are;
The company will not fly me home to my city of record. They flew me home for the first 3 years I was here then stopped.
The will only pay a certain amount of my electric bill. This is what they stated but I must admit I have not gone over the said amount but nevertheless the company will still stick it to me if they want to even though my contract says we will pay all electric, water and gas.
They will give us 25% of the profits above the target in the form of a profit share check. This year not withstanding the last 3 years they didn't pay anything.
A 3% pay raise a year. We have received that most years but twice they didn't pay that item.
I'm sure other pilots have many more items the company is not paying.
