Apparently the nasty-graham McDonald's Operators received from McDonald's USA legal several weeks ago claimed that communicating with others gave some possible advantage
to "our competition".
In other words, McDonald's Operators leak proprietary information. Nothing could be further from the truth.
If there are leaks in the McDonald's system - Many of the leaks come from McDonald's upper management during discussions with Wall Street analysts.
Case in point, is it any wonder that McDonald's major competitors were ready to launch new value platforms at the same time McDonald's USA launched the $123 menu? McDonald's management had been publicly blabbing about the new menu during much of the fall of 2017.
Prior to launch the analysts knew more about the $123 menu than McDonald's Operators.
The rest of the leaks in the McDonald's system come from employees of McDonald's outside advertising agencies and PR firms.
These people are loyal to no one and are always networking for their next job. It's important they establish connections with reporters who cover the advertising business. They sing like birds.
So Operator leaking is not the problem. Trying to impress shareholders and disloyalty among agency people is the problem.
