Most employment situations are “at will” . . . you can apply get hired and resign or get terminated. If you qualify and get hired, you show up for work to get paid the money you need. You quit when you want to quit . . . I don’t think that should be too much of an ethical dilema, unless of course you’re tied down with some sort of employment contract or agreement, especially when the company spends money on you for relocation, training, uniform, etc. . . .
