We have to share the computers at work, so I can't make much progress with my work.
There isn't a computer for each person at work, so I can't really make much headway with my work because I have to share with others.
この場合、次のような言い方ができますよ。
ーWe have to share the computers at work, so I can't make much progress with my work.
「職場でパソコンを共有しないといけないので、仕事が捗らない」
to make progress で「はかどる」
ーThere isn't a computer for each person at work, so I can't really make much headway with my work because I have to share with others.
「職場では一人一人にパソコンがなく、他の人と共有しなければいけないので仕事が捗らない」
to make headway で「捗る」とも言えます。
