Over the past 30 years, salary never goes up, I know because I saw the salary today is same as my first salary 30 years ago, I’m not disclosing my age, so don’t be too paranoia, but the price of everything goes up thru the roof, the only person who salary goes up are (ikr, salary must kept secret because it is case sensitive, don’t tell anyone else!), ok, enough rant! Try to tell your kids to work for a salary in the future, I think they could barely afford a piece of beard!!
End of story! Ciao!
So if you know your worth and you know that the salary you're being paid is not worth it, then its up to you to talk about it with your boss or whoever you're meant to talk to about it. Another way your salary can be increased is through promotion and sometimes that means that you're getting double work than what you work before, and the increase after then might still not be worth it cause of the work that has been doubled up.
Part of the problem is companies busting up unions that try to fight for fair wages. Companies like Wal Mart will fire anyone that even talks about forming a union. They have lots of anti-union propaganda at their job orientations as well.
This is how inflation works actually but talking on op for 30 years passed seems to be very impossible yet on my country it do adjusted between on those kind of gaps of years.
