Yeah, voluntary resignation is a bit different, naturally. Um, basically here's some
short examples to clarify how I meant:
(Note: This specifically applies to Sweden and I obviously can't speak for any other systems or cultures present in other countries)
1. If, say, the employer needs to cut down on staff due to financial reasons, an employee is failing to meet necessary quotas or other similar reasons (mostly, as you say, redundancy reasons); Then you need to give said prior notice as the employee is not necessarily directly at fault (things like underperformance is usually not considered a direct fault of the employee) and thus they should be given ample chance to prepare themselves to move on as opposed to being tossed out of their office and being potentially left without any further income before they can find an alternate source of income.
2. If the employee however, say, leaks confidential information, intentionally sabotages operations or otherwise misbehaves to the point of warranting termination (especially if they've already received warning(s) for misbehavior); Only then may an immediate termination be legally accepted as it would be made directly as result of the employee's actions meaning the employee is indeed at fault.
Anyhow, @Anoni, this is probably getting a bit too off-topic so I'll digress. Feel free to message me either in PM or IM or whatnot if you'd like to continue discussing it!
Talking about Ventus, where is she?
I believe she posted, alongside MrRazot, that they were leaving the forum, at least for the time being. They also posted their contact details for discord for anyone who wanted to talk to them. Should be in the temporary section
