If true that will deliver an interesting conundrum to quite a few. It has been reported that BRK contracts were the highest contractor rate. They close down and thus your contract is null & void. What then? Do you have to reapply to another agency to continue working for the same customer? It has been reported that the other agencies offer lower rates and slightly differing T's & C's in general. What then? Same job, increasing profits for customer, reduced income for contractor. That will test the mettle and resolve of many.
A true contractor would continue to bill their customer at the same rate as previous, or even a long belated increase.
