You're more likely to end up on management's shit list and/or let go for turning in a petition to them regarding cuts/freezes in benefits/compensation. In fact, I'd bet it would be the given response and you'd also have to live with the guilt of getting others fired as well if you actually convinced any poor, gullible soul to sign it.
Even if you only include facts and don't make any inflammatory statements... they do realize exactly what they are doing. Your pointing it out to them shows you may not have a very clear grasp about how businesses change, and will make you and anyone that signs it look naive, aggressive, and unprofessional along with showing very poor judgement.
Businesses do sometimes reduce or freeze bonuses, compensation and other perks. The answer is not a petition. It is a sit down with your immediate supervisor to discuss your situation specifically, and if they can't do anything about it, then your next step is to find another job that pays you what you think you are worth. Not a petition. This is not an outrage like them refusing to pay workers overtime or a other seriously egregious whistleblowing situation where you call out and condemn this behavior; this is a business decision regarding perfectly legal, across-the-board adjustments to compensation/bonuses that have been occurring for years apparently, and made likely to position your company's bottom line in a better light. So yeah, really don't do this.
This reminds me of the interns that had a fit about the dress code at a company and thought it would be smart to turn in a petition to demand changes after being told by their supervisors that they would not be allowed any flexibility. The person organizing it thought it was a great idea and sure to make their voice heard and open a discussion... instead they learned about how businesses aren't going to put up with any push-back from the workers when they are told this is how it is, and no just because you don't agree with something doesn't mean you group together and try to force them to change anyway. They were all fired.
The proposal was written professionally like examples I have learned about in school, and our arguments were thought out and well-reasoned. We weren’t even given a chance to discuss it.
But instead, you assumed you knew better (despite being in a position where the whole point is that you don’t have experience and are there to learn) and then went about it in a pretty aggressive way. A petition is … well, it’s not something you typically see at work. It signals that you think that if you get enough signatures, your company will feel pressured to act, and that’s just not how this stuff works. A company is not going to change its dress code because its interns sign a petition.
