If a previous employer called to ask you about a bug in the code you'd written for them, how much time and energy would you be comfortable investing in helping out?
Let's say you left your previous employer a few months ago, on reasonably good terms. You might hold a minor grudge against the company because you didn't get the raise you deserved or because they wouldn't give you the QA resources you'd asked for, but it was generally an amicable parting. Certainly, you still care about your old teammates; you'd be happy to share a beer with them. Especially if they're buying.
A few months later, one of those teammates calls you with a problem. They're trying to debug a problem in a code module you used to own, and which you knew really well. Can you help?
Well, can you? Will you? Should you? Just how far will you go out of your way for the old team... and the old boss?
I think most developers would give an old employer 15 minutes of phone time without a second thought. Maybe 30 minutes, if it's still in a casual format such as instant messaging and if the conversation is kept general ("Did you look at the gargleblaster?" rather than "Let me pull up that JavaScript code...").
And certainly—at the other boundry condition—few developers would spend a whole weekend fixing the old application for free.
But somewhere in there, you draw a line. Two hours? Four? I don't know where it is for most programmers, or where it ought to be... and I wonder what the "right answer" is.
I expect that company lawyers would freak out if they thought existing employees were asking for your help. After all, your previous code was written as a "work for hire" so the company owns the copyright. If you change a semicolon in their code now, though, that wouldn't be so. (The fact that lawyers would object, of course, makes this effort even more attractive.)
Professional pride is a factor. If the bug is visible in some way (such as on a public website you developed), I think a lot of programmers would itch to fix it. For portfolio reasons, if not a sense of perfectionism.
Also, there's such a thing as good karma. Refusing to help a previous teammate (never mind the company affliation) might be seen as burning bridges socially, if not professionally. Which makes it all the more important to figure out where the line ought to be crossed; at what point do you cease to be a kind person, and become a gullible chump who's covering up for your successor's inadequacies?
Plus, some segments of the development community are connected more by shared technology than they are by the name on their paychecks. Many years ago, I knew several developers who worked on the software to run hotel reservations systems. A developer at Quality Inns had no qualms about calling an ex-colleague at Ramada Inns or Best Western for help (which incidentally, is the same software that United is finally replacing). In modern terms, developers who work on open source applications
Well, I left a long-term employer 7 months ago on good terms. And I have been asked to help out with a few bits and pieces. I did this happily, but only because I knew it would take me 5 - 10 minutes to answer the questions asked. Anything longer than that, and frankly I would be looking for billable time. I don't see why ex-developers should feel an obligation to helping out past employers, although clearly there are different circumstances where help may well be appropriate, as shown in your examples.
In my experience, the period of notice is spent tying up loose ends, completing documentation, etc., etc. So there should be no reason for old employers to come knocking if that's happened!
...or, rather, another opportunity.
I did write a paragraph about the mitigating factors when the developer left to become an independent consultant, but I yanked it because I feared I was becoming too tedious. Perhaps I should have left it in, because the questions from a previous employer that exceed that "quick phone call" should sound like "ka-CHING!" to a consultant.
I agree that the period of notice is supposed to tie up all the loose ends. But I wouldn't swear that it does. Even if the employer intends to use that time to download the contents of the departing employee's brain... all too often I've seen people with ten days to go documenting what they think is important rather than what the employer might really want to know. That's when they're not treading water, just waiting for those last two weeks to be up.
I would give +-15 minutes remotely (over the phone, Skype, etc.). I wouldn't write any code myself, but wouldn't mind looking at it, and suggesting ways to fix it.
I believe this is something an employer should always keep in mind, and that it is very important to put continuity efforts in place. If an employer does not apply these measures, it is not my problem, and the sooner they realize this the better. If a development organization properly applied things like unit tests, thorough comments, light documentation covering the essential, exposing developers to multiple models over time, etc., there should be no reason that a request for help should be longer than a quick phone call.
Doing maintenance work over weekends for previous employers would be billable. This is to say you are allowed to bill, since many employers don't allow you to do work for anyone else while you are working for them. My current contract stipulates such a condition.
None. You shouldn't help at all. I know this sounds harsh, but you are risking a lot. You can get sued, you are now privy to confidential information. Your current employer may also setup grounds for dismissal (especially if they are a competitor).
I would never risk my neck for a previous employer.
you my friend have said the one thing the author of the article didn't even touch (and this magazine is for CIO's).
you are 100% correct. doing anything for a company without a contract could result in your getting sued and why even risk it.
do you actually think that your old employer would put their neck on the line for you? of course not?
all transactions you perform for that employer ended when you walk out the door. anything further should be done on a contract basis and a clear scope of work for you to get compensated for.
