Bird v British Celanese Ltd, Court of Appeal on March 8th 1945, reported at [1945] 1 All ER 488 and [1945] K.B. 336.

if in accordance with express or implied contract terms an employee is suspended from work without pay because he has committed some act which is in breach of his contract, the contract continues to exist during the period of his suspension and non-payment of wages in resect of that period is then neither a breach of contract nor an unlawful deduction from wages.

For relevant general notes see Deductions from wages etc and Suspension of employee/general .
