Teachers’ Unions II: Protecting Bad Teachers
One stock conservative talking point is teachers’ unions are a primary cause of educational woes. If only unions could be eliminated or significantly changed, then education would improve significantly. Those defending unions argue that education would be worse without unions and some contend the effort to eliminate teachers’ unions is part of a plan to transform public education into a for profit-system to benefit a few well-connected elites.
Since the debate is so politically charged, it is difficult to objectively address the issue of whether teachers’ unions harm education or not. However, I will endeavor to address the matter as objectively as possible and acknowledge that as an educator and union member I am biased. As such, my arguments should be reviewed with due caution. Now, to the matter at hand.
One standard criticism of teachers’ unions is that they harm students by protecting bad teachers from being fired. If unions could be changed or eliminated, then bad teachers could be replaced with good teachers and the students would benefit. One variation of this criticism is focused on the practice of last-in first-out: those hired last are the first fired, should firings occurs. The concern is that teachers are retained based on seniority rather than ability, which can result in bad teachers remaining employed and good teachers being fired. Retaining bad teachers and getting rid of good teachers would clearly be bad for the students.
On the face of it, this criticism does match a plausible narrative about unions: since they exist to protect dues paying members, the leadership is not overly concerned about the quality of these members. As such, they do their best to see to it that no one is fired and thus bad teachers remain in the system. These bad teachers, obviously enough, do a bad job at teaching students and this harm can impact them throughout their entire life. Being able to fire these bad teachers would open positions for good teachers. The good teachers would do a good job, thus benefiting the students. From this it follows that eliminating unions would be good for students.
In the case of the policy of firing the last hired, the claim is that eliminating unions would result in merit based hiring and firing, so that when there was a need to fire teachers, the bad teachers would be eliminated regardless of seniority. As such, being rid of unions would improve things for students.
One easy and obvious reply to these criticisms is that they are not criticisms of unions as such. Rather, they are criticisms of specific practices: retaining bad teachers and retaining based on seniority rather than quality. There is nothing essential to a teacher’s union that requires that it mandate the retention of bad teachers nor that it mandate a seniority based retention system. To use an obvious analogy, there are countless examples of bad policies followed by corporations that do not arise simply because a corporation is a corporation. Roughly put, the bad policies are bad not because they are policies of corporations but because they are bad policies. As such, they do not provide grounds for the elimination of corporations. Rather, the badness of a corporation’s policy provides grounds for changing that policy. The same applies to teachers’ unions: the badness of a union policy serves as grounds for changing that policy, not elimination unions.
It could, of course, be argued that by their very nature unions must protect bad teachers and that it is impossible for them to do otherwise. Likewise, it could be argued that corporations by their very nature must have various terrible policies that harm the public. If so, then solving these problems would require eliminating unions and corporations. However, this view seems implausible; although people’s ideologies do often compel them to see things this way.
A second reply to these criticisms involves considering the facts of the matter. If unions protect bad teachers, then highly unionized districts should retain more bad teachers than districts that are less unionized. But, if unions do not protect bad teachers, then districts should have comparable percentages of bad teachers (adjusting for other factors, of course).
As should not be surprising, the debate over this factual matter tends to involves anecdotes about bad teachers and intuitions about unions. While anecdotes can provide some illustrative examples, they do not provide a foundation for general conclusions. There is, after all, the classic fallacy of anecdotal evidence which involves doing just that. Intuitions can provide some guidance, but by their very nature they are feelings and thoughts one has prior to considering the evidence. As such, anecdotes and intuitions do not suffice to show whether unions are good or bad in regards to the retention of bad teachers.
Fortunately, Professor Eunice Han has conducted a study of the claim that unions overprotect bad teachers. While it runs contrary to the anecdotes about bad teachers that cannot be fired and intuitions about overprotective unions, the evidence shows that “highly unionized districts actually fire more bad teachers.” Somewhat ironically, districts with weak or no unions retain more lower quality teachers than highly unionized districts.
As Han notes, stronger unions reduced the attrition rate of teachers and increase teacher wages. Because of the higher salaries, there is greater incentive to remove bad teachers and good teachers have a greater incentive to remain. This nicely fits the conservative mantra that top talent can only be kept by paying top salaries, although this mantra is usually just applied to people like CEOs and not workers.
In contrast, weak unions (and the absence of unions) increase the attrition rate of teachers and decrease teacher wages. As such, good teachers will tend to leave for areas with strong unions while bad teachers will often end up in areas with weaker unions or those that lack unions. The statistics show that unions have a positive impact on teacher quality and that the myths of the overprotective union and the irremovable bad teacher are just that, myths unsupported by facts. This also nicely matches the conservative mantra about compensation: lesser talent will settle for lower salaries.
It must be noted that since this issue is so ideologically charged, those who oppose unions will tend to regard the study as biased and might offer “alternative facts” of their own on the grounds that what they believe must be true. Likewise, those who favor unions can be accused of accepting “facts” that match their views. This is, of course, a much larger problem than the debate over unions: if there is not a shared set of facts and methods, then no rational discussion is possible. Only the howling of ideological stances driven by desire for profit and power.
