Pros

Great if you need to work the graveyard shift due to children at home. Good job for someone who doesn't like talking to the public or who can work independently of others. No traffic going to work/home from work (Broadway and I-25)

Cons

Pay is decent, but they give you 'night differential' for your night working hours. That means that if it's a paid holiday or a vacation day, you don't get the night differential - you just get your base pay, even though you never work 'daytime' hours. You never get the opportunity to work holidays (double pay) and overtime is very stingy. You have to prove your dependents for insurance purposes (birth certificate etc) for them to be covered. Vacation/absence time is the same - and if you take more than 5 unexcused absences in one year, you are on final termination warning. Not good for those whose kids get sick! No flexibility with hours. No chance to move into a daytime position. Low percentage pay increase rates - 0 .08 for example. I'm here because I need the job.

Business Outlook

Pros

No one standing over you. Team leads are good people. Benefits are good.

Cons

low pay, with no room for advancement. If you show the supervisors you are a good worker... they will give you more work until you become a bad worker. Work is unbalanced with the new people doing the blunt of the work while people that have seniority sit back and drink lemonade.
