Pros
Only one: low/no bar of entry. All you need is a bacherlor's you'll never use. On the one hand, this is good for newcomers or newly-grads to enter the industry and gain some very transferable (and you'll want to transfer at some point, see below) experience. On the other, it is bad because new hires consistently know very little and must be trained, slowing your capabilities while the pace of work marches ever faster.
Kontras
Here, you will be treated with the bare minimum and expected to constantly perform above maximum. You will be paid 1/2 to 2/3 of industry average, such that management can schedule you for constant, mandatory overtime and only then pay you close to the average. You will be required to be "on-call" and to clear up your schedule without compensation. You will be pressured to stay for an extra 4 hours, twiddling your thumbs idly, needlessly waiting for management to sign documents they could've signed during your normal shift. You will be ordered to ignore mistakes and to overlook regulatory inadequacies. This is a place that will exploit you with unrealistic deadlines and constant management hostility. This is a place that was not long ago class-actioned for wage theft and lost. This is a place without integrity in quality, which will encourage or force you to smudge truths or lie to pass studies or restore equipment to operation. This is a place that praised its employees for record profits at a year-end luncheon, only to have its own employees complain months later about not having anything left after rent and bills. Indeed, your job here is not to validate equipment nor to protect product quality. Your job is to ensure that production never stops, no matter the damage to product quality, production processes, equipment, or morale. There is no respect here. Terrible benefits. No growth opportunities. 5 PTO days per year, and 4 sick days per year that expire every year. Inadequate training. No professional development. Goalposts and timelines shifting with such frequency that weeks of prep can be wasted. You will not come home after work and feel proud of what you've done. Until I finally learned to tell management to back off, my stress was such that even my personal relationships began to strain. I pray you have the choice I didn't and steer clear of this place. But if you don't have that choice, treat this place as the two-year community college degree that it is. Learn some skills, beef up your resume, then move on.
