Unless there’s additional pay for doing so, quite literally not my problem. A good manager from day one of a new hire should be ensuring a smooth hand-off is already prepared in the event of separation for any reason.

Arguably, during your last two weeks that is your job - the entirety of your job. So not additional pay, but your final pay check is for doing just that.

The entire point of giving two weeks notice is a courtesy to your employer to facilitate a smooth transition period.

If you DGAF about that, you might as well give no notice.

Employers rarely give notice when terminating an employee.

Every tech company I know of gives plenty of notice. If it's performance issues then you've got months of notice via a PIP. If it's a layoff then you get severance which is effectively notice.

Of course not. Voluntary notice periods never have been made out of fairness, it is and always was about self-interest.

Employees give two weeks to be nice and not burn bridges with people on their team.

Employees who are angry at their employers may often give no notice at all.

Employers don’t give notice in layoffs because disgruntled employees are not productive and are a liability.

Employers don’t give notice in terminations because they don’t want them working for two more weeks.

You owe your employer nothing. Your co-workers, and others who will come after you, however, are humans with aspirations and problems just like you.

Interesting! Handing off job responsibilities is definitely an important aspect, especially for more tenured employees.

It's called a transition plan and your manager should work that out with you during your notice period. Who will pick up your responsibilities? Accept no new work. Don't attend regular meetings. Don't do overtime. Disengage from instant message such as Teams or Slack. Do everything via email CC'ing your manager. Start to work from home during your notice period. Your single focus is hand off and get out ASAP.
