Here are some ideas I'd like to see a union fix for our industry:
Agesism in tech
Non payment for employees or contractors
Protect programmers refusing tasks on ethical grounds
Establish ethical standards
Better working conditions - quiet offices, not open floor plans
Working from home when practical
minimum vacation time (not pooled with sick days)
No 2 day exploding offers
Dignity in job interviews
(Can you guys think of any more?)
