If your employer is docking your pay due to client non-payment, it's important to understand if this is legal. Generally, a loss of pay can be considered a punishment, and your employer should follow a due process, such as issuing a charge memo or requesting an explanation. If your pay is directly linked to performance through variable pay, the situation might differ. If the proper procedures weren't followed, you may have grounds to challenge this through a court or tribunal with the help of a local lawyer.
