I started a new job 4 months ago and this was a career pivot for me as I entered a new industry. I also went from working for a company of 50 people to 15000 people so fairly new to the corporate lifestyle.
My manager did interview me and is very well aware of this industry being new for me. Upon joining, I was barely given any training sessions, rather was just told to learn everything myself by using the web. I took it as a challenge and kept giving my manager frequent updates however never got a response/feedback if I am following the correct path.
Once training period was over, it was tough to get any job expectations and responsibilities clear from my manager as he would never attend any meeting we scheduled. He had excuses of running late, that he will meet at a later time but there was never any initiative from his end and I had to keep following up with him. Anytime my manager says he will meet me, it easily gets pushed 2 weeks for one reason or the other. When we do meet he answers my questions, gives me tasks for the next week. There are also instances where he has to get back to me on something/send me resources to move forward/ connect me with SPOCs but it rarely ever happens as he forgets or puts it low on his priority list which in turn affects my productivity and keeps me stuck to a point where I have to remind him a couple times.
Earlier this was a new and I gave him the benefit of doubt but now it is more like a pattern of me running after him for giving me resources to succeed at my job. There is also no clear communication/ transparency from his end and I rarely get replies from him on teams.
How can I bring it up with him/senior manager as I do not want this to come bite me later.
Thanks in advance for your suggestions.
