A union shop steward is addressing a union meeting...

"Comrades. We have agreed on a new deal with the management. We will no longer work four days a week."

"Hooray!", goes the crowd.

"We will finish work at 4 PM, not 5 PM."

"Hooray!", goes the crowd, again.

"We will start work at 10 AM, not 9 AM."

"Hooray!"

"We have a 150% pay rise."

"Hooray!"

"We will only work on Wednesdays."

Silence...then a voice from the back asks, "Every Wednesday?"
