If the punctuation is joining two independent clauses (which are, essentially, complete sentences in themselves), use a semicolon rather than a comma. The reason to use a semicolon here rather than making it two separate sentences is to indicate that the separate clauses are closely connected. In this case, the employees were working long shifts because the number of employees had been reduced.
