College does not seem to consist of strictly 18-22 year olds, anymore -- it has not for quite a while, actually. Good luck to you on your education project. It is a good idea to focus on study while you are in school.
As for unionizing a work place, one needs the support of an established union--there are a couple that represent restaurant employees.
I have shoplifted in protest before. — thewonder
I used to do that -- back in the 1970s -- until I got caught and had to pay a hefty fine. My partner was nearly arrested at a local grocery store for sampling chocolate covered something or other that were sold out of a bin. He was very humiliated, and was not doing it for politics, but because it was a convenient snack item while he was grocery shopping.
I spent a lot of time in gay bars once upon a time. (I'm 72.). Cruising for sex, of course, and to chat, listen to the music. I sometime drank too much, which sometimes is the point. So, at this point I've settled on being as suave or gauche as I am. I am what I am.
The IWW was/is an interesting group. The do exist, but nothing in the way they did 100 years ago. But I think their theory, their songs, their attitude was all good. You familiar with Billy Bragg -- a British folk singer?
Here's his version of the Internationale.
The Internationale
Billy Bragg
https://www.youtube.com/watch?v=v85NWc0RIKc and Pete Seeger doing the original version in French
Stand up all victims of oppression
For the tyrants fear your might
Don't cling so hard to your possessions
For you have nothing if you have no rights
Let racist ignorance be ended
For respect makes the empires fall
Freedom is merely privilege extended
Unless enjoyed by one and all
So come brothers and sisters
For the struggle carries on
The internationale
Unites the world in song
So comrades come rally
For this is the time and place
The international ideal
Unites the human race
Let no one build walls to divide us
Walls of hatred nor walls of stone
Come greet the dawn and stand beside us
We'll live together or we'll die alone
In our world poisoned by exploitation
Those who have taken now they must give
And end the vanity of nations
We've but one earth on which to live
And so begins the final drama
In the streets and in the fields
We stand unbowed before their armor
We defy their guns and shields
When we fight provoked by their aggression
Let us be inspired by like and love
For though they offer us concessions
Change will not come from above
Billy Bragg
So, again, good luck to you, and much success.
