All for just 1,25% of salary or maximum of 49€(~53$) /mo. This union is for Technology industry and it has ~120 000 members. Labour legistlation is not good, go unions!
It also includes unemployment benefits and it means we are able to keep 45% of our salaries for 300, 400 or 500 days depending on the employment length before unemployment. (This is paid by the unemployment fund).
Without being part of the fund you get only 800€/mo of unemployment benefit.
I was living good on the unemployment funds, until it was about to end and needed to find work which I luckily did.
