An employer is liable for acts done by employees during their time at work.
This applies to all forms of discrimination. However, an employer can use the defence that they have done everything that they reasonably could to prevent it from happening.
An employer can be liable for acts committed by the employee where the employee has carried out their job in a particular way.
But, also for acts that have nothing to do with the employee's job, but were committed during work time. Unless it can be shown that the employee was "on a frolic of his own", eg. a prank.
