and how do I react next time they don’t greet me?
I started working at this department 3 weeks ago. I went into the office I now work at, greeted 2 coworkers I’ve already worked with, they looked at me, said nothing, kept talking to themselves.
How am I supposed to interpret that?
To me this is disrespectful, maybe you disagree?
Then, as I was working, I saw both of them staring at me. What am I supposed to do when that happens? To me this signals hostility and passive aggressiveness.
I separate private life from personal one but even I know that the least you can do is to greet your coworkers, unless you want them to quit.
Just remember that you all are cogs in the machine, and also nobody owes you anything - including a greeting.
My guess is your workplace has a low personal life/low banter culture or even policy. If thats the case, you may be talking to people who know this and dont want to get in trouble, or to people whose souls are crushed and theres no life behind their eyes.
Don’t take it personal.
I’ve worked in both kinds of environments. I prefer high banter/high friendship environments but i work fine in either.
