Also, what chances of advancement is available to her? Why chance does she have to improve her standing within the company? Is she in a dead end job that requires her to deal with lots of unnecessary bullshit that could be avoided if only the company changed a couple small ways in which it operates to make things go smoother?  Is there any anonymous suggestion box available for employees to make inputs on how to improve the workplace? Has her bosses / mgr / superior ever done anything to convey that she is NOT a valued or appreciated worker, and merely viewed as a number, a labor cost, or a potential liability / expense that can be cut without any thought or concern whatsoever?

I work at a job and busted my ass for my first full year doing hard labor that is dangerous, dirty, and incredibly damaging to one's body.  After the 3 month review I got a little $0.55 raise, but after the first year, they avoid anybody that even ASKS for their mandatory (according to employee manual) review!  They begin to treat you as a number, a line item, or just another serf.  Even though there are sometimes opportunities for people to advance, they don't even inform their other workers of the job opening. They try to hire outside, and leave people in dead-end jobs because it's easier than retraining.

I busted my ass for these jerks, and when some meth-head coworker fucked up, and I wound up getting two ribs broken in 3 places, they didn't do shit. No drug test for asshole, and no help with my bills...  I wasn't missing any limbs, so, hey - no big deal, walk it off kid!

They turn & walk away if you try to ask for your 1 year review (even after 1.4 years), and try like hell to avoid anybody from advancing within the company, or asking for a review or a raise...  They sometimes make a general pay scale increase of $0.03 per hour, but that doesn't even keep up with inflation, and never takes into consideration the amount of time on the job, or the quality & quantity of work performed! So you have lazy assholes that never do a damn thing, and often come in drunk, or so tired they fall asleep on their forklift, or crashing from a meth habit, and these pricks get the same insulting pay increase of $0.05 that a hard working, smart guy who is running a crew of 7 other people gets...  Don't you think the guy running the 7 man crew should maybe have a more merit based pay increase?  What about if the drunkards & assholes all get a $0.05 raise every 6 months, but the guy running a crew of 6-7 guys doesn't see shit on his paycheck?

You have officially disgruntled that employee, and there is little you can do to un-piss them off.

I regularly warn people about how most GOOD workers don't get paid enough for the shit they do.
