Museums Sheffield, which was unsuccessful in its bid for Major Grant status, was awarded £341,000 in transitional funding from the arts council today.
This follows a previous award of £190,000 in transitional funding from ACE, bringing the total to £531,000.
The money is designed to cover the next four months and will help Museums Sheffield maintain its current exhibition commitments while it undergoes a restructure.
The museum is to make 21 posts redundant at the end of March, with a further 23 redundancies expected in late summer.
Nick Dodd, chief executive of Museums Sheffield, said: "It is with great sadness that we lose so many colleagues who have made such a huge contribution to the cultural life of the city, but we will work with our partners to explore a sustainable programme for exhibitions and activity going forward."
