I am working in German company and my job contract states following:
Der Arbeitnehmer erhält für die unter vorstehend Ziff. II. näher bezeichnete Tätigkeit ein Bruttogehalt in Höhe von X Euro bei 21 Arbeitstagen,.....
The employee receives a gross [monthly] salary of X euros for 21 working days for the activity described in more detail under II
and for the holidays it mentions:
Der Arbeitnehmer erhält pro Kalendarjahr Anspruch auf 24 Arbeitstage Urlaub bein einer 5 Tage Woche.
The employee is entitled to 24 working days of vacation per calendar year with a 5-day week.
I have been working for past 1 year for the whole calendar month, regardless of number of working days. I just noticed that in February, 2022 I was paid only for 20 days as there were only 20 working days. But in March, 2022 we have 23 working days but I am only being paid for 21 days. This has been happening for past year or so.
Am I entitled for a compensation for the extra hours I put in. I am not sure, but sometimes I feel like my boss exploits my situation as I do not understand German law the way he does.
Could someone who has an understanding on this topic enlighten me?
