When I was a Sys Admin in USA, your salary never increased unless you left the company and took a job elsewhere. Those were your raises, and it's why SA turnover is so high and how even companies just treat them as a dime a dozen now a days.
That is more the aftermath of the dot com days when there was a severe shortage of SA people. Big companies would train people and get them certified and those people would turn around a leave for double the salary. So companies quit training and did not expect anyone to stay over a year.
They continue to not be training, or doing a bare minimum of it. My current company thinks sending me to a 3-5k class a year is apparently more valuable than increasing my salary 3-5k a year. It's not.
