"The Union Meeting" joke

A union shop steward was addressing the workers at a union meeting...
"I am pleased to advise all of you that we have agreed on a new deal with the management. We will no longer work four days a week."
"Hooray!" the crowd yelled.
"We will finish work at 4 PM, not 5 PM."
"Hooray!" the crowd yelled again.
We will start work at 10 AM, not 9 AM."
"Hooray!"
"We have a 110% pay increase."
"Hooray!"
"We will only work on Tuesdays."
Suddenly, the crowd fell silent, until a voice from the back asked, "Every Tuesday?"
