I am afraid it is pettiness, jealousy, and bitterness. No one owes you anything. You don’t have to stay in a shit job where you aren’t valued, and aren’t well compensated. That is entirely YOUR CHOICE. Go to HR for a raise.
Good money and good roles don’t typically just land in people’s hands. They work hard, and upskill etc.or are smart enough to hold those roles.
( I’m not management material, don’t want that responsibility, and am nowhere near as smart as my manager. They work bloody hard, and deserve the comp they get. I don’t begrudge what they have.Nir that if my more senior colleagues.)
Not saying this is the case for everyone, but you have a choice. I was on a really shit wage where I was struggling to make ends meet for 6 months during the pandemic and after it eased off.
Most of my spare time was spent applying for roles online, updating my cv, writing covering letters, and upskilling at my role where I could - I applied for hundreds of jobs, spoke to every agency in the area and further afield, and managed to get a few interviews. I kept at it until I got something that was right for me, and was a salary I was happy with.
Life is unfair sometimes, but you just have to persevere. Find a way if you can, start your own business, get a side job, study if you need to, change jobs.
Obviously lots of people are not well compensated for the good work they do (many nurses atm). But the fact that you and your colleagues aren’t doing anything to help your situation and would rather gossip and go to HR says all I need to know.
There will always be someone better off than you, and likewise someone that is worse off than you. People can spend their money on what they like and it’s none of your business. I’m certain you wouldn’t want to be told what you could and couldn’t spend money on, nor where you were allowed to shop for your work clothing!
