I work at a quickly growing company that started as a mom and pop and is now being taken over by a corporation. They have made some changes (which I really like to see!), the latest and greatest one being forming a HR department.
We have an all manager meeting between six department heads that I may soon need to be a part of. The problem is, I butt heads with one of the other managers pretty bad. They are not nearly as willing to go through these changes that are being made and has recently turned their frustrations on my department and the changes I've personally made within it. I've talked to the GM about this but they are friends that share information and, to frankly put it, the GM doesn't have much of a back bone and often puts up with the manager's horrible behavior. Since the manager's department helps bring in income and is currently under the itense eye of the corporation, the GM rarely pushes back on things that don't quite make sense but would be an easier short cut to make the department look better.
The new HR manager is aware that the manager is a problem (I have yet to address my concerns) and is making progress to change things around here but it's an uphill battle.
The meetings relate to employee and department concerns as well as reports. From what has been said by other managers, it's a complete free for all that can get quite heated and I worry that it would not fly by the company that has absorbed us if they really knew what was said and how things were handled. I also worry I will be attacked and, without proper mediation, I will have to defend my position and department to people who hate it (my department gets to be the rule enforcer within the work we perform which impacts all departments). Is it acceptable to request for HR to sit in on these meetings?
Edit 1: For clarity, the HR department is just the one person! They are not included in the manager meeting and I don't believe the GM has intentions of changing that. The all manager meetings included all managers before the HR manager was onboarded by the corporation and my promotion. The GM claims the meetings are mainly centered around profits. My department does not make money and is self sufficient so I have not pushed to be included.
