30-year-old quits her job of 6 years after new coworker, Ben, keeps stealing her work and credit, and faces zero consequences despite multiple complaints: ‘I addressed it with my manager, director, and HR. After a year I simply couldn’t take it anymore’ – FAIL Blog

What makes this particular situation worth paying attention to is the six-year part. This was not someone new to the company trying to find their footing. This was someone who had already proven herself, already had the relationships, already had the track record. None of that mattered once the pattern started. The managers who knew her well enough to promote her were somehow not well-positioned enough to recognize what was happening right in front of them, or were not motivated enough to do much about it once they did.
