Situation
I work in a small company of ~20 people. While this company was a startup ~a decade ago, it is not anymore. The people working there aren't "wild teenagers" anymore; some have kids already. Things like pensions become more important now, but have been repeatedly postponed - if I understood correctly, it first came up 9 years ago.
There are other issues that differ from department to department and from person to person, like micromanaging, no opportunity for growth or not supporting work life balance. However, for example the team spirit is excellent and we would like to try and turn this into a place with a future for their employees (sounds dramatic, but you get the point).
Issue
We had a meeting after work to discuss this. We came to the conclusion that we want to open a discussion with "management". However, that's where the size of the company comes into play: For example, "management" is only 2 people who work 10 meters from us and we talk to daily. There is no official process for serious requests because we just get up, walk there and talk to them directly.
Current plan
Our current plan is to write a letter and give it to management as a group. The letter:
[Formalities]
We would like to bring the following to your attention. As employees at [Company], we add a lot to the company's success, good work atmosphere and development.
We think that our contribution is not appreciated enough. We think it is time to take steps towards operating in a way more appropriately for a company of this size, so that [Company] stays an interesting workplace in the future.
Appreciation of the team's efforts can manifest in several ways. We look forward to hearing from you inside the next 2 weeks what your plan in this matter would look like.
[Formalities]
Some of this sounds weird/awkward in English but I did my best to translate the meaning.
Question
We are not yet sure about all this (well, hence this question) and are still wondering, for example, if the letter should be delivered by the whole group (seems like "ganging up") vs one representative (but who?). However, to sum it up in one question:
How can we start a dialog about work conditions with "management" in a rather small company?
