WOODS V WM CAR SERVICES [1981] ICR page 666

In our view it is clearly established that there is implied in a contract of employment a term that the employers will not,without reasonable and proper cause, conduct themselves in a manner calculated or likely to destroy or seriously damage the relationship of trust and confidence between employer and employee. Caurtlands Northeren Textiles v Andrew [1979] IRLR 84. To constitute a breach of this implied term it is not necessary to show that the employer intended any repudiation of the contract;the tribunal's function is to look at the employers conduct as a whole and determine whether it is such that its effect, judged reasonably and sensibly,is such that the employee cannot be expected to put up with it;British Aircraft Corporation v Austin [1878] IRLR 347. The conduct of the parties has to be looked at as a whole and its cumulative impact assessed. Post office v Roberts.
