I joined 3M in 2014 as a business analyst. I was a happy new employee, eager to do different things. Above all I wanted to learn. All worked fine first. After some time I realized that the management does not care about new employees, they uninterested in anything we do and they always complain about our performance (even though we do our best).
I accepted this as part of the job but it started to get worse, after some time my managers were just not interested in me and my work anymore. They were power hungry, their only goal was me make my life miserable in order to force me out of the company. Started by giving me long hours and then, when I refused to leave (because I love what I do) they started to give me impossible tasks; or tasks that were unrelated with my job description but nevertheless he had been giving them as a reason for demoting me.
I still don't understand how this happened: how does a company who advocates diversity and fairness can allow managers to behave this way.
Anyhow, I left in 2020 on my own and I am happier now.
I still want to think this is all an exception and that other managers are not as wicked as the group I had to deal with.
