What is the dollar investment of one all-hands employee meeting? Forget the logistics: the venue, support staff, communications, and other costs. For a minute, just consider the salaries involved.
Assume 10,000 employees making an average of $50,000 per year, or about $24 per hour. For a two hour meeting (with 30 minutes of additional time for employees to show up and then get back to their desks): 24 times 10,000 times 2.5 is $60,000.
