Managers 1 (Bad)

Sorry i have not posted in a few days, we just got 2 puppies and they have been a handful

So i have 3 people above me in my store. 2 of them on the same level and the other is above those 2. One of the people directly above me did something that was upsetting, but first a little back story. We have meetings once a week and those 3 people tend to have schedules from 9am to around 5pm and everyone else generally has a schedule similar to 10-7 or 12-9 but the meeting is from 9-10 so we all have to come in at 9am leave our meeting at 10 (and on some days we literally leave at 9:15am) just to come back in an hour or 2 for our working shift. I for the past 4 months straight have worked 9am to 9pm because of this being as its not a good idea for me to drive 30 min home and 30 min back so i work the whole 12 hour shift. Yes i know i know i am not the only one who does this and i'm not complaining that i do because i understand. What upsets me is for some reason one of those 2 people has the nerve to call out of the meeting at 9 and show up for his 12-9 shift at 1pm and then leave at 8:15 and tell us to finish up while hes gone. No. No no no. That's not how this works, you can not lead like that. I have done a 12 hour shift every week once a week for that past 4 months. Normally every 4 months i get either that day off and just come in for the meeting or i will do 9-5 and get a break. These guys maybe once every 6 weeks are expected to be there till 9 and when they are expected to do so they don't? What makes this even worse is the selected individual i'm talking about when they do arrive spends 90% of his day using his personal laptop to do his second job so hes getting paid 2 jobs for working the same hours. Look i am not against a little extra money, i am not against leaving early, but its unfair to the rest of us who do our jobs and his. I would love even once a week at work to just sit in the break room and do a 2nd job on my personal laptop. That would be the same as working 6 days a week but only working 5. That income alone would be an awesome bonus and he does it every day while we do his job. It is unfair to everyone and it is very upsetting. You are not the only one who does not want to go to work. Your kids are older then i am so your not raising children. You drive a car worth 2x what mine was when it was brand new. Theres no good reason you can give for doing what you do. Sorry i know i rant but between being limited on time and being upset about this i just threw all my thoughts out there. Tell me what you think in the comments below, after working for a long time in your life do you deserve to be allowed to do that? Should i be upset for my manager giving me tasks or leaving early or calling out? Is it even my concern? Let me know what you think.
