1. Its in the corporate by laws not their contract. They get it whether they like it or not. Current management holds it over their heads. To paraphrase one of my several "A" friends there: We demand a pay raise, management counters by implying profit sharing makes up for less in pay rates.

2. Its capped to IRS limits. I'll never make enough for this to matter but for many of them 9.8% (this year) puts a number of their A's into the cap and they get cutoff.
Also incorrect.
