The Dutch cantonal formula sets the amount of money that has to be paid to an employee if he/she gets fired and is due to circumstances entitled to a "golden handshake"
A * B * C = amount of money.
A - Stands for the amount of full years worked. Years worked on age unto 35 count for 0.5, years 35 up to 45 count as 1, years 45 up to 55 count as 1,5 and years on 55 or higher count as 2
B - Stands for current monthly payment including all steady extra's like holiday money, extra's for shifts, bonuses etc.
C - is by default 1 but can be set to 0.5 when the employee is partly responsible, to 0 is the employee is fully responsible, to 1,5 if the employer is at some more fault and to 2 if the employer is extremely at fault
So let's say an employee gets fired due to being ill for to long and the employer has legally not done enough to reintegrate the employee during his illness, so getting fired is not legally justified. An employee can go to court and demand his job back, but when this is not possible he would get money due to the ABC formula.
Example:
Employee has worked full years from age 40 to 60 at the company and gets fired without proper reason.
A*B*C
A = 5*1+15*1.5+6*2 = 39.5
B = let's say monthly income is 4.000,-
C = 1
Giving 158.000,-
Now the employee was ill and employer acted against him, treated him wrong, broke the rules on integration etc.. That would put C at 2 giving the employer 316.000,- and if the employee himself did not do enough to integrate but still there was no ground to dismantle the contract than C gets set to 0.5 giving the employee 78.000,-
Hope this explains it properly.
This formula even tho used widely in the Netherlands has never been an official instrument but more an unofficial guideline to make court cases rule in line with each other and has been replaced by new official rulings in 2015.
