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, Im not disclosing my age, so dont 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, dont 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!
The price of goods goes up automatically, but as for your salary you will have to ask for it, if you need an increase in salary and you think you deserve it. Hardly will you see any employer that is ready do an increase for you without you asking for it cause they will assume that you're okay with what you're being paid, so for that they wouldn't give you any increase in salary.
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.
