For what it’s worth, in most cases, “with cause” is misunderstood. “Fired with cause” on UI’s end typically means the employee was fired for something egregious and/or illegal. Stealing company property, committing fraud using company resources, gross negligence leading to someone getting injured, etc… Simple underperformance isn’t typically enough to exclude you from claiming UI.

Even though people will colloquially say that being let go for underperformance is “with cause”. It’s typically not correct, and won’t hold water if the former employee decides to appeal the initial UI denial. But companies have a vested interest in supporting that colloquialism, because if people believe they don’t deserve UI then they won’t try to claim it, (or won’t try to appeal it when their initial claim is denied,) which keeps companies’ UI payments low.

Mass has a lot of employee protections that other states dont but this is also really company dependant. Some big companies also dont fight unemployment claims, ever. I was HR at both a large and small company. The small company fought everything the large company had a policy of never fighting an HR claim no matter how egregious the firing cause. They felt it wasn't Wirth the cost of defending a potential suit. So this is heavily dependent on state and company. Sometimes also on the HR, I always tried to find a way not to contest but other HRs may not have put that much work into pushing back if they were told to contest it.

Also references are often just dates of hire and title in most companies. But that's totally separate from unemployment reaching out to HR Unemployment has a series of official questions you have to answer and one of them is "are you contesting this claim". You're friends companies may just be saying "no".
