Employment and the recommended retainer remain the same in months with holiday. The hourly contractor model is reduced in proportion to worked hours.

The monthly amount is not the whole story

What the comparison reflects

Employment

Greater certainty and minimal business risk.
The employer handles administration with public authorities.
Typically easier access to loans, predictable sickness and unemployment support, and a higher pension.
Holiday, public holidays, doctor visits and paid leave remain a company cost even when no work is performed.
Less flexibility for tax planning and designing one’s own long-term financial security.

Contractor

Without material additional risk, the hourly contractor cost should match the average company cost of an actual employment hour.
No work means no invoice. Employment cost includes holiday, public holidays, doctor visits and part of sickness absence.
The company typically does not pay contributions, meal allowances, sport cards, travel expenses or severance pay — subject to the agreement.
The agreement can be tailored and ended under its terms.
The contractor bears more risk: potential penalties, liability, unpaid invoices and their own tax, health, social and sickness insurance.
