How about managements spawn. That will get you more places than anything else will. Hell, they will hire two at a time to fill those jobs, one the spawn gets paid to do nothing much what so ever and their 'assistant' that does the actual job and gets paid bugger all, only to be fired when they are blamed for the spawns fuck up.
Petitions are as stupid as fuck, seriously, sign those and you screw over your career. To do that stuff you absolutely require the protection of Unions. Unhappy with company policies, secretly get it in writing, forward it to https://wikileaks.org/ and work on finding employment else where. Don't like bad management, catch them breaking the law and report them via https://wikileaks.org/ (whistle blowers are persona non grata in most corrupt democracies, especially the US, thanks, Uncle Tom Obama).
Actually catching and implicating management in prosecutable crimes is a smart career move, if you don't get caught. It creates many vacancies at the top, corrupt management types will drag down those corrupt employees who assisted them ie Wells Fargo, lots of job opportunities created there
