EDIT: I have reorganised my question because all responses so far have been off topic to the questions I actually asked.
What I would like to know is:
Am I acting within my rights?
Are my employers breaking the law by trying to block this meeting?
Should I have gone about this somewhat differently? Bare in mind that management are pretty useless about making any kind of change (unless it suits them).
Please see below for context.
Recently I have been dissatisfied with management's response to my concerns at my work. (This is a burn account for anonymity)
Speaking to colleagues, I found that they also had concerns and were not even bothering to raise them with HR / management because they knew nothing would happen.
I have considered for some time that some kind of union would be beneficial to the majority of employees and decided after the above mentioned consultation that I would actually do something about it.
Now it is important to know that a sizeable proportion of my colleagues are a little older, perhaps have children or sick relatives and would not want to rock the boat too much. Entirely respectable.
In contrast, I am young, unattached, dependent-less and work in a rapidly growing field. I have no concerns about job security which is why I felt that I, rather than someone else, should be the one to speak out. Because the repercussions can only affect me.
I sent out an email, siting some general irks of myself and others to those that it would concern from my office. Scheduling a drinks event at the local restaurant / bar / bistro and encouraging those that shared our concerns to come along and a plan could be made for something to do about it.
This was received VERY well by the recipients.
2 days later however, I am dragged into a meeting with a supervisor and am essentially threatened to cancel the whole thing (They weren't sent the email by me). This is the UK so no such formal reference to being fired but the connotations are there. This particular supervisor has threatened this before and it doesn't work. I am not scared of being fired.
I have been told (warned?) that I will have a meeting with the head of the company in the near future. Is this a place to make a case for my actions? Do I just shut up? Is there any reason I haven't thought of that means I should reconsider going through with this?
I will make sure to update with future steps and outcomes.
