<human>: Sorry for the length, this situation requires a bit of background. Thanks for reading. 

One of my staff members (I'll call her Jessica) recently took a position in another department  within the company. I immediately began searching for her replacement, and found two excellent candidates. Prior to interviewing either candidate, another member of my staff gave me three-weeks' notice because she decided to move out of state. 

I had two openings and two great candidates (I'll call them Joanna and Chelsea) - the two open positions are similar enough that one of the candidates may fit into the newly open role. I proceed with interviewing both candidates, and offer each of them a position on my staff as of yesterday. I offered Joanna the first position (lower-paying and a step down), and Chelsea the second position (higher-paying and a step above the first position).

As of this morning, Jessica, who left my department, has realized she does not enjoy her new role and wants to come back and reprise her old position. She knows the job inside and out and is a company asset. If I hadn't offered the position to another candidate, I would gladly welcome her back. But I have already made offers and both candidates accepted. 

I met with two execs at the company today to try and find a solution. The execs don't want to lose Jessica as an employee and want to giver her what she wants - her old job back. They want me to call Joanna and tell her that we can't hire her after all, and call Chelsea and offer her the first position instead of the second (which was Jessica's). 

I can offer Chelsea the first position at the pay rate of the second position, which puts me in a little bit better of a place. But I just don't feel right about all of this - I feel like Jessica made a mistake and she should deal with it instead of dragging me into this. I will look foolish and make the company look bad to the new candidates for changing my mind, but if I decide not to give Jessica her job back, it will be frowned on by the execs (my bosses) and Jessica will probably leave the company - which will be blamed on me.

What the hell would you do in this situation?

Can you give me the gist of the text in a nutshell?
<bot>: Hired two new employees for two open positions yesterday. Old employee wants her job back for one of the open positions. Not sure whether to oblige her and bosses, or to move forward with new hires and lose great employee.
