Here's a rough draft for the WOL law:

[hider=WOL]

The Workers League Act of 3901

Men over the age of 16 shall be eligable for enrollment in the Workers League-A nationalized union of skilled/unskilled laborers dedicated to bolstering the economic and industrial infrastructure of the city. Enrollment is [s]mandatory[/s] voluntary. 

The [b]WOL[/b] shall garrison groups of no more than 200 men at designated spots (I'm assuming picked by the industry captains of the city? i.e. The nobles) around the city wherein they shall set to work building farms, factories and any infrastructue as deemed appropriate by the aforementioned authorities. The High Council shall have executive powers of veto in project designation. 

The WOL shall provide:
[list]
[*]two meals a day for every WOL member, except every seventh day where a third meal containing meat shall be provided[/*] 
[*]A sleeping cot, and WOL uniforms[/*] 
[*]Minor medical attention not requiring surgery or sorcerous procedures shall be provided[/*] 
[*]Clothing shall be provided[/*]
[*]one day, or 12 days per season of rest[/*]
[*] A minimum of a 12 hour work day[/*] 
[/list]

A regimental system of organization shall be mandatory for each garrision. 'Commanders' shall be responsible for performance of their respective garrisons. WOL workers shall be eligable for positions of leadership only below that of Commander- which will be appointed by (the High Council?) A quota of production will be maintained by each garrison.

The details are mostly for fluff. The law itself will definitely have an affect on the city. Feel free to change any wording/organization etc.
