Grants to the voluntary sector in Wales should last for at least three years, according the final report from the independent commission established by the Welsh Assembly to review the sector's relationship with government.
It argues that while the Voluntary Sector Partnership Council - which links the two sides - is working well, the sector suffers because Assembly members frequently fail to attend.
The commission focused on the dangers of contracts lasting only one year.
"You only get six months' work out of a 12-month contract," the commission told social justice minister Edwina Hart.
The minister is also facing calls for the adoption of clearer exit strategies.
Mark Isherwood, Conservative spokesman in the Assembly, demanded six months' notice when grants are continued or removed.
The commission was established after the Welsh Assembly elections last June.
