"Union Meeting" joke

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?"
