Mary is not impressed with the level of work being done by John. Mary's best course of action to avoid a wrongful dismissal claim from John is to:

Select one:

a.provide John with appropriate notice under the Employment Standards Act, or pay him the equivalent in lieu of the notice period

b.tell John that if his performance does not improve, he will be forced to resign from the position

c.tell John that he should quit the job as it is just not working out

d.ask John to offer a letter of resignation with proper notice
