What's up sherbros. TLDR version at the end. A couple of weeks ago I was promoted at work. I now occupy the charge of operations manager or whatever the company owner wants to call it (not a big fan of titles). It's a small logistics/customs clearance company of about 14 people. It used to work like this: The owner had a guy running the operations (5 people inside the office, 3 outside) and another one in finances (3 people total). Plus his brother that is developing a new service, a secretary and a few administrative. Seeing that the relationship between the operations manager and the team was pretty bad which lead to a lot of things going south and basically everybody at the office not putting much into their work he decided to promote me to run the team. The owner told me that the other guy made a big deal about nonsense and had everybody stressed out. Now the other guy is supposedly going to be more on the street (going to customs and solving problems) which is the part I don't like and I'm not strong at it. It was made explicitly clear that I'm at the same hierarchy as him. The owner was pretty clear: I make the decisions inside. Anything regarding the people working there from incentives to punishments go through me and is 100% my choice. Anyways. I knew this guy was going to start pulling some crap on me. My first action was to stop a sanction that the other guy was pushing against 2 coworkers who made a human mistake that costed us literally a few bucks. He hated that. Another example.. last week I interviewed a guy for my former position (I'm getting 2 people) and I really liked his profile. When I showed him the resume (out of cortesy, didn't had to) he said "oh, I interviewed this guy... there is something wrong about him, I can't remember what.. don't hire him". There is a shortage of specialist in what we do (and what we can afford) and this guy is not working at the moment, has like 20 years of experience and really needs the job. At the beggining he told me that the guy had a terrible reference from another job, then he said maybe it wasn't that and he was misremembering and he didn't like the attitude of the guy in the interview.. he said it was "too relaxed". Hiring has been terrible in the last couple of years. I saw a lot of people passing by doing a terrible job and lasting a few months leaving us with more problems than anything. I said fuck it and hired the guy. He is starting tomorrow. Today I heard him talking on the phone with our clients telling basically that a guy left (an operations guy at some point they tried to make supervisor but failed at it) and that I was taking charge.. and that it was The owner > Him > Myself. Also I just checked my emails a while ago to see an email from him directed to me and a woman that works in my area asking for explanations about a situation that happened today (which he misunderstood) and asking what we are going to do to avoid that in the future. Like I have some explaining to do to him. Since getting promoted I tried to make him participate or at least I ask him about his thoughts on why of the decisions I'm making. I'm trying to make it easier for him but I'm tempted to blocking him out completely This exact same thing happened to me years ago and the other guy ended up being fired when he decided to go against me. So.. what do you guys think? at this point I have 3 options: 1) Fuck it and tell him that I don't own any explanations to him. We go to war. 2) Cooperate with the guy and slowly making him understand I'm not there to compete with him. 3) Wait until my area is strong enough and literally take everything away from him and leave him with only the things I don't want to do. TLDR Version: Former boss can't understand I'm on his level now. Couple of days in and he is still acting like he is above me. Should I streamroll over him like I did in a similar situation on the past or should I be the bigger man and working him slowly and peacefully until everything ends up where it should be? @Red Beard.This is a #workMOBtactis situation. Your input will be welcome.
