"time period" = "month"
> Die Vergütung ist nach der Leistung der Dienste zu entrichten. Ist die Vergütung nach Zeitabschnitten bemessen, so ist sie nach dem Ablauf der einzelnen Zeitabschnitte zu entrichten.
translates to :
Remuneration shall be paid after the services have been rendered. If the remuneration is calculated according to time periods, it shall be paid after the expiry of the individual time periods.
"after the expiry" != "immediately after the expiry". It can be one second, or a year. 614 BGB clarifies that you are not entitled money BEFORE you have rendered your part of the contract.
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.
The legalese for what you describe would be "mit Ablauf des Zeitabschnittes". Which is NOT in the legal text here.
> (...) 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
This is settled law. This has been settled law when people still got their Lohntüte at the end of each week.
