Pros

Willing to training on things you haven't done before.

Cons

They don't care about their employees and you are just a cog in their wheel to make them more money. My advice would be to just work there to get training on something you've never done before and move on to a better company that appreciates you better

Pros

None! Not even a sensible stepping stone company. More likely to hurt your carrer, than help.

Cons

Systemic, serious quality issues have been present and intentionally ignored for years by senior leadership. Cronyism amongst leaders is rampent, which only continues the never ending cycle of horrible decisions resulting in horrible quality, resulting in further horrible decisions, on and on. Employee surveys are reviewed in a manner to find out who said what. Follow orders, don't bring up anything negative and maybe you'll last long enough to be a scapegoat for something going wrong or a client being disappointed. Beware curious leaders! Your efforts to engage your reports, peers and effect positive growth for the company are strongly discouraged (under the table of course, they'll make up whatever they need to in order to punish you).

Factory Job

Pros

Decent pay for little to no experience. The only part of this job I enjoyed was the people I worked with.

Cons

There is no actually animal care. You are doing a job to raise mice with the most basic of care. They are in little shoe boxes with cardboard rings as enrichment. They say they don’t want to waste them but I would throw away more mice than we would keep. They also didn’t pay me for a month which is illegal according to NC law. And they didn’t pay for coworker for two months.
