Yet another example of how clueless managements are. They are incapable of actually assessing value of the actual work performed. So they use proxy metrics like LoC, hours worked, in-person presence in the office.
If you want to paid very well, then churn out thousands of lines of rubbish code, be in the office for 70+ hours, attend their meetings, pay rapt attention to their PowerPoints and laugh at their jokes. Bingo!
