The subordinating conjunction in the sentence is “unless” and the relationship it demonstrates is “condition” .
The subordinating clause in this sentence is “unless everyone contributes” and it establishes relationship of condition to the main sentence. Subordinating clauses start with a subordinating conjunction, have a subject and a verb but they do not form a complete sentence.
We cannot order the banner for the gym unless everyone contributes.
Subordinating Conjunction: unless
Relationship: condition
