This irks me more than anything.

Why should the employee give 2 weeks notice but the employer can unemploy you between 11am and noon? I know it’s professional. So, let’s do the professional thing - give me 2 weeks of notice or 2 weeks of pay if you’re concerned about security.

There are all kinds of asymmetries. 55 mins to interview the candidate, btw do you have any questions for us? You’ve got 5 mins.

One justification for companies to do this, is to ensure the employee doesn't damage the company property or reputation. An employee told 2 weeks in advance that he will be sacked is a dangerous mind.

What i never understand though, is companies forcing employees to train their replacements, after which they are fired.

Perhaps companies ought to publicize their employees records or performance, if only limited to qualitative ones, so that during quit time, employees are not blackmailed for getting a good record of employment.
