Yeah it's a big responsibility and sorry but the mins just aren't that high.
How many diverts/medicals/true airplane emergencies have you even dealt with after 1000 hours in the plane? How many go arounds have you done? Windshear encounters? You'll be flying single pilot too and doing IOE and teaching landings and doing all kinds of sorts of things you never imagined, trust me. Nobody "owes" you an upgrade. It's not something you earn, your number simply comes up and you meet the minimum requirements. Now you're saying you want the minimum requirements lowered.
Sorry... you can meet the same minimums the rest of us did.

And what do you want the union to do? Amend the CBA? That would require an agreement with the company... it's not like they can just force the company to the table and say "you have to sign this LOA!" Contract isn't amendable for a few more years now.. If you're getting bypassed you'll just sit less reserve. Why be in such a hurry to give up your QOL? And the PIC hours don't matter, we have plenty of FO's getting hired at Delta or CA with very low PIC.
