First, if you need to use a service like this to get stuff across to your boss, this is my feedback to you:
Fix yourself (specifically the issue you have bringing stuff up with your boss) or (if they're the reason you feel like you can't talk to them about something) find a new boss. No amount of anonymous feedback is going to fix a poor relationship with your boss. And it's probably not going to fix the other stuff, either.
Anonymous feedback is terrible:
- It's too easy for a manager to disregard or mentally down-vote as being from a bad apple or someone they don't see eye-to-eye with.
- Without being able to put your feedback in context of who you are, where you're coming from, and what your relationship is with them, it could also make what you're saying a lot more hurtful than you mean it to be. For example, they might think it was from someone else. And maybe your feedback, coming from someone else they work more closely with, would really hit a nerve for some reason.
- It also seems unthoughtful to deliver anonymous feedback to someone without giving them some way of addressing the feedback, perhaps giving you some feedback of their own, should they think the feedback was flawed in some way.
Instead, we need to be having real conversations. If those aren't working, maybe you're in the wrong place.
