[suboptimal]

Yeah, legacy COBOL probably equals "huge corporation." I assume, then, that there's an employment agreement covering this scenario.

It's an ethical dilemma, but in my opinion the fundamental right to earn a living (basic economic freedom) trumps the letter of an overly-restrictive contract, _if_ the employee's outside activities don't impact the employer in a material way. That's not law, that's just my opinion, and I realize it could be a bit of a slippery slope. However I just don't see how a company can own an employee's time away from work (again unless the employee is competing in the employer's direct line of business). See the work of Brandeis.
