Can you explain the "bad work rules" to me?

The training department is getting told to prepare for 500 pilots per year (we only have 700)

If you plan on staying at a regional for a long time, or trying to work as little as possible (we do work a lot, min days off 12), or don’t want to fly an airplane that makes you a better pilot, then Piedmont maybe shouldn’t be your first choice.

probably 2-6 months, just a guess

12 days off minimum, the bottom half of the lines have only 12 off, even the top ones are only 14 off. That’s mainly because we do shorter legs, nothing much over 2 hours, so are days are inefficient, which results in working mores days per month.
No trip, duty, or sit rig, one would be nice.
At least we have a minimum credit of 4 hours per day.

It isn't my first choice by a long shot but no one is hiring 1500 hour FOs at the moment.

Where would one end up in the interim?

3 crew bases. CLT is senior. That leaves PHL and MDT, which are about 2.5 hours drive from each other. Seems like most are going to PHL as junior FOs.

What is commuting like to PHL while one can't hold CLT?

It's an AA hub, so if you're flying in from an airport with a lot of flights to PHL it may be doable but you'd probably still need a crashpad.
