I have been in a new job for a few weeks. There have been lot of instances of casual sexism - language and behaviour - that I've noticed. I raised some of these these verbally with my line manager that relate to one specific colleague, He suggested we speak to the colleague's line manager and set up a meeting to do so.
Then my line manager went on leave and while he was away, there were more instances of sexism, now involving the language/behaviour of other colleagues. I was at the stage where there were so many instances of inappropriate language use/behaviour that they were all swimming round my head and I was forgetting/confusing the details, so I wrote them all down and emailed them to my line manager. In my email I stated that I was not making a formal grievance but rather wanted the management team to be aware of what I was experiencing. I read the company policy on grievances beforehand: it says that raising issues informally and talking them through with your line manager in the first instance is the best course of action.
The meeting between my line manager, the line manager of the first colleague I reported to him, and I, has now been cancelled, and I have since been invited on my next working day to what I think is a formal meeting with my line manager and an HR member. I have been invited to bring someone with me to this meeting. This feels like a very formal reaction to something I stated was not a formal grievance. My line manager says that because I sent in a written account, now HR has to be involved.
Does this sound like it's being treated like a formal grievance, even though I stated it wasn't? Should I take someone to the meeting? if so, why would I need to? Do I need legal advice? I'm concerned that I'm going to be treated like the problem.
