As an involuntarily retired full-time virtual L2, I'm insulted by the idea I was "part-time". I worked on code that kept systems and reports running. The way it worked was this:
Code worked, I'm golden, I'll do my LWD or other corporate compliance thing, or maybe even take off early.
Code didn't work, stick with another iteration until it did. Most of the time that took up all of eight hours. For deadlines, I put in entire weekends on testing and Q/A. I was salaried, so I got paid for 40 hours but they got more than that on balance.
It's an insult to the workforce and frankly it's why morale is so poor both inside the company and among customers. Friends and family—you know, the typical targets of employee incentives to sign up customers—have had many problems with billing and quality of service. Company brushed them off.
Now that I'm gone, these mostly former customers have told me they're glad they dropped AT&T, and that the same guy who skipped MNF or a Saturday BBQ to work would be laid off, much less be accused of being "part time."
And by "work" I mean "at home" in an office that I equipped with a Herman Miller chair, a standing desk, and an array of monitors. Company "hotel spots" always felt like trying to work from a plastic seat on a city bus. If I was lucky I'd score a second monitor for the day, but usually not.
The only way I'd put in these kinds of hours at their office would be for double the salary.
