So its our fault for not making a union? Also nothing to do with 40 year decline in consumer rights & stagnated wages & heavy influence of money in politics. Also, to quote Stephen Colbert, its the ribcage's fault that victim got knifed.
Surely a union would help avoid this exactly kind of things, I can assure you. Once I kept my job thanks to a union when there were mass layoffs at a company I worked for. Also, a union would probably have negotiated something better than an "at will" contract, which I assume Twitter employees are bound to.
