I have been in a startup for around 1.5 years. I am getting very less money (below industry average), and almost no career growth. Sometimes there aren't enough projects to keep me busy, while other times the salary that I receive is delayed by almost 15 days, because some other huge client hasn't paid yet.
So, I decided to focus on upskilling myself, so that I can switch to a different company. I bought some online courses. But, I want to upskill as soon as possible. Should I focus more on upskilling and less on company's work, or learn new skills only when I have free time ? I am very new to this, so I don't know how people do it?
By focusing, I mean doing less of company's work.
