That's actually exactly what it means. Immediately after the end of the time period, the employee is entitled to the money and the employer has to pay interest for each day after that.

I would suggest to talk to your company's legal representative. You may be surprised.

The legalese for what you describe would be "mit Ablauf des Zeitabschnittes". Which is NOT in the legal text here.

The LAG Köln disagrees with your interpretation:

> (...) Im Falle des verstetigten Bruttomonatsentgelts tritt diese Fälligkeit gemäß § 614 Satz 2 BGB nach Ablauf des Zeitabschnittes, bei einer Monatsvergütung also nach Ablauf des jeweiligen Monats, ein. (...) [1]

This means the payment is due as soon as the month is over and according to § 286 (2) 1 BGB, the employer is immediately in default

With that interpretation, salary would /never/ be due.

This is settled law. This has been settled law when people still got their Lohntüte at the end of each week.
