The Types of Past Practices
There are three categories of past practice. The "contract clarifying past practice" is the strongest type and the "contract conflicting past practice" presents the weakest legal argument.
Contract clarifying past practice: These practices come into being when there is contract language that is vague or general. The practice defines the general language.
Example: The contract language reads, "The company will allow union stewards reasonable time off from work to attend union meetings." The general phrase is "reasonable." For many years the company has allowed stewards to attend monthly union meetings and three times a year the District council meeting. Every year one steward and the officers get time off to attend the National Union convention. This past practice now clarifies what the contract means by "reasonable."
This is the strongest type of past practice because it is backing-up negotiated language. In most cases an employer must bargain to change the past practice, and they cannot change it if the union doesn't agree.
Independent past practice: This is a practice that is not addressed by any contract language. Most often these are "benefits" that workers take for granted and so were not included in the contract.
Example: There have always been vending machines in the cafeteria. Management cannot just decide to remove them. Parking has always been free in the company parking lot. Management cannot just decide to begin charging employees.
Independent past practices can be terminated by management for the following reasons:
-
If they can prove that there has been a significant change in the original conditions that started the practice;
-
If they can prove significant ongoing employee abuse of the practice;
-
Finally, if they notify the union during contract negotiations that they will end the practice during the next contract.
Even under the "change in conditions" and "abuse" situations the employer must bargain with the union before ending the practice.
Most arbitrators will not extend these past practice rights to "work methods."
Example: Management wants workers to run 3 machines instead of two, claiming new technology makes them easier to run. The union probably cannot claim it is a past practice that workers only run two machines. However in most cases the union can demand that management bargain over a change in working conditions.
Contract conflicting past practice: In this case the practice clearly conflicts with the contract language. These are the hardest to prove, with most arbitrators coming out on the side of saying the contract should prevail. With a contract conflicting past practice an arbitrator may look at practices that have existed for very long times, happen very frequently, very clearly conflict with the contract and were very clearly known to both parties. In these cases the arbitrator may rule in favor of the practice.
Example: The employer has never given Union Representatives "points" under the absentee system for attending union conventions, even though there are no provisions for this exclusion in the absentee system which is part of the contract. This has been going on for ten years. The union notifies management each year as to who will be attending the convention. In this case although the practice conflicts with the contract it probably would be considered a valid past practice.
The employer must notify the union of its intent to end the past practice and must bargain with the union, if the union requests to bargain. After bargaining the employer may end the past practice. |
