Suppose a manager at the Post$-$it Brand has recently become aware that employees are taking office supplies home and taking longer coffee and lunch breaks than the personnel policy allows. The manager finds these are widespread practices and wants to solve the problem. The best way to do this would be to a$.$ fire all those who have taken office supplies, and suspend those who have taken too much time. b$.$ change the code of ethics in the personnel policy manual to prohibit these practices. c$.$ call the police and arrest both the "time" thieves and the office supplies thieves. d$.$ let the union know about the problem during next year's pay negotiations. e$.$ make the corporate culture encourage more ethical behavior.
