I worked in Switzerland, the 13th month wasn't a bonus, they simply took your salary, divided that by 13, that was your monthly payment and you got 2 of them in December.

Also many bills are due on the first of January for the whole next year e.g. insurance. So it was kinda like a holiday and large bill windfall, but it wasn't additional to salary.

That was just one company, maybe other countries or employers are different.

This. You know your yearly salary (gross and net). Then you get it in different schemes depending on country and company. Some I now are:

- 14 payments (extras in June and December)

- 12+1 in December

- 12 + 2 x 0.5 (one extra in June and the other In December)

I believe dates were pick to match Xmas and Summer Holidays, two big spending anomalies

Anyhow you always negotiate yearly gross.

Not in the Netherlands. I always negotiated monthly gross. Then your 13th month and summer bonus suddenly actually feel like bonuses, even if the company includes it in the full yearly amount.
