Last year, Mukluk, Inc., a small family-owned manufacturer of mud and snow boots was bought by a larger organization when the founder of the small firm decided to retire. With the change in management came many changes in policies, procedures and organizational culture. It used to be a "laid-back" and informal organization, where any line employee could talk personally with the founder. Now, rules are strict, production quotas are high, and line employees are grumbling that the supervisors are "slave drivers." What has changed about this organization that will make it prone to unionization?

A) the collective bargaining climate
B) the exclusivity of the employees
C) the psychological contract
D) the situational instrumentality
E) the essentiality of the jobs
