In Hoffman v. Caterpillar a restricted employee was refused the opportunity to train on a new machine because her supervisor believed that her incapacity would make it impossible to operate the machine with acceptable speed. The court held

A under the ADA failure to train is a materially opposing employment action that can be challenged as discriminatory.

B the employer engaged in dissimilar treatment provided the employee can prove that she is able to operate the machine.

C the employer isn't obligated to reasonably accommodate the employee in the training process because operating the machine is not required for her current job

D it is the employee's prerogative to select when to request a reasonable accommodation
