Here's a song that doesn't cover strikes, just the general woes of being white collar.

BRING BACK THE EIGHT HOUR DAY
(Charlie King)

Say you work at a white collar job
You're paid at a fixed monthly rate
But you come in for meetings a half hour early
You're working a full hour late
Then you sit for an hour in traffic
With the rest of the overtime drones
There's a latchkey kid you must chase off to bed
For you eat a cold supper alone

CHORUS: So, bring back the eight hour day
When did we give it away?
There's so much to do
When the work day is through
Oh, bring back the eight hour day.

They've got cellular phones for your car
They've got notebook PC's for your lap
When you crawl off to sleep you stay close to your beeper
Now why do we stand for that crap?
They tell us we have to compete
No, we're tired of footing the bill
Eight hours for work, eight hours for rest
Eight hours for what we will.

CHORUS ^^
