Companies are run by people (not machines), everything can be negotiated, dont get blocked by what you see from Job Ads and Bulletins.
Companies don’t always know what they are doing, many just pretend that they do, question the status quo, ask why 5 times, find the first principles. find out why people do things.
Salary/Compensation is never fail and equal, there’s no sense comparing your’s with your co-worker, WE GET WHAT WE ASK FOR. state your desires/skills during interviews (be sure to have the right skills for your job before you demand tho)
Blame is not for failure, it is failing to help others or ask for help, asking for help is something people are too embarassed about. there is nothing embarassing about wanting to improve yourself or your work.
