what's the answer

Allison worked as a bartender and cashier in a bar. She occasionally had to leave the bar, but would lock her till before doing so and take the key with her. There are no other keys. One evening, Allison's cash was short $300. She urged the employer to call the police, but the employer did not. The next week her till was short $1,000 and she was fired. The employer withheld her last paycheque as compensation for its losses. Allison filed a complaint with the Ministry of Labour for the deduction from her wages. The employer pointed to a form Allison had signed when she was hired that stated: "If a shortage occurs, full payment is due immediately. If for any reason this agreement cannot be met, I authorize the employer to deduct the shortage in full from my next pay." a. Did the employer violate the Employment Standards Act by deducting the till shortages from Allison's final pay in these circumstances? b. Explain your answer. c. Would your answer change if three people shared the same till? Explain
