After working for 1-5 years, when we ask the boss for a salary increase, or when we switch jobs to "pick up" an offer, are we confident enough?
Do you dare to "wave your sleeves and not take a bug with you" without a salary increase? Did your supervisor, manager immediately after making the request?
Agree, in order to keep you. However, the reality is often...
The technology is not too hard, and the rest are ignored.
