I'll give you an idea of the culture my direct manager perpetuated... When I was interviewing I was "sold" on the great tech I would work with, the culture and opportunities, once I started started, he wanted to be "best buds" he wanted to grab lunch together all the time, although not a smoker, he tried to get me to take numerous "smoke breaks" with etc...Problem here is he liked to gossip. he would belittle my co-workers he wasn't fond of and ask for my assistance in making their time with the company "uncomfortable". I wasn't on board with this, but never indicated as much because I didn't want to suffer the same fate. It wasn't long after I started I realized much of what I was "sold" on in my interview was non-existent, the technology I was told I'd work with either didn't exist, or was managed by an MSP and our hands were tied to much of the administration. A good portion of the "equipment" sits powered off and is obsolete. A full "server room" with redundant connections, AC units running full blast for servers that aren't even running. electricity is being wasted by the truckload for dormant servers, switches and other infrastructure that isn't running. Wasn't maybe a month or so and I got a bad feeling and felt I made a mistake coming onboard. As time went on I withdrew from his invites more and more often and watched the mistreatment of others continue, until I couldn't be quiet any longer. I voiced my concerns to his management, and was blown off. I was told it was simply my "opinion" and not valid. That we were a "team" and had to watch out for each other. This same director said he was "well aware" of everything happening" and saw nothing wrong, although clearly he wasn't. Being a upbeat high energy person I didn't give up, I planned to make the best of it, No company is perfect but I didn't expect it would get worse.
Fast forward about a year. I was able to really get to know my colleagues, made some friendships and the issues created by this manager had people looking to quit, many of whom had been there many years before the manager in question started. Knowing sooner or later something bad would happen I started documenting everything I witnessed.
A few specifics that I witnessed:
He took credit for others work constantly, not just "my team did this" but rather, he would personally take credit another individual on his team did.
In addition to this he plagiarized others, he would frequently ask myself or others to summarize a project or write documentation on how or why something worked, he would then cut and paste this into a communication or email as if he had written the work himself.
Among the rest of the "technical" people in our department he was considered a "fake it till you make it" guy.
We often overheard him lie to executives and other department personnel about technology or even the status of a project he was responsible for. He would then turn around and belittle this person or chuckle because he knows he "had them fooled" .
Very often he would use industry terms in effort to confuse users, many times in the very wrong context because he himself didn't really know the answer but would rather lie or make something up than admit he didn't know.
I recall a specific time where I assisted the top executive in our company, he had an ongoing issue that I was a handed because my manager couldn't figure it out and I assume because he realized "being the top expert" and continuing to not resolve a seemingly simple issue was making him look bad.
From my brief conversations with the executive, I found the root cause and resolved it, I also realized he had been lied to for a long time about the issues. When I returned to my department proud that I was able to resolve the issue, I wrote a quick summary of my findings and copied the executive and my manger (mostly so he couldn't take credit like usual) My manger was upset that I fixed the issue before consulting him, and that I summarized my findings to the executive. He said he didn't like telling them details, specifically because they didn't need to know, and something about "job security the less they know"
I could go on and on about the things he is doing that either hurt the company or at the least make a hostile culture for the staff he has on his team. Sooner or later the company will either be sued or have a massive loss due to his incompetence. I am glad I jumped ship when I did.
Knowing his manager (director) was not going to help or resolve the issues, I reached out to HR, sadly this got me nowhere either as they simply referred me back to the departments director. No "official investigation" took place, no one was interviewed, no one who could corroborate my complaints was contacted., The director again basically blew off my concerns.
Defeated by the obvious cronyism going on, I decided to start looking for a new opportunity. I couldn't stand by and see this person mistreat my coworkers, lie to others and basically destroy the IT department.
During this time my manager was made aware of my complaints, and he decided try and make me uncomfortable, asking for odd tasks to be completed with tight deadlines assigning me tasks with a specific outcome with zero direction or resources to accomplish them, started micro managing me, likely to try and find cause to term me he even said in a 1 on 1 that there will be recourse for my "actions" Luckily I recorded this conversation as well as a few others and have them saved in case anything ever came of it.
This manager is still there even though a provided several documented scenarios and provided them to HR, I am very sure executive management has no idea the real reasons I left, I am confident they would take action, hopefully they see this and do.
