Re: ( Estoppel 101)

We the Canadian Union of Public Employees Local 110 (hereinafter called the Union) claim there is a difference between ourselves and the Winnipeg School Division (hereinafter called the Division).

In that the Division is now administering article 9 to our detriment, the Union finds it necessary to file the Estoppel below:

…………………………………………………………………………………………..

Estoppel (1.1):

.

– The parties have consistently/historically accepted the past interpretation of Article 9.

– The matter was never discussed in negotiations.

– The Union took this as an indication that the practice was working for both parties.

– The Union relied on this practice without detriment.

Therefore:

– We (The Union) assert that the Division is Estopped from varying the practice during the life time of the Collective agreement met between the Winnipeg School Division and CUPE Local 110

Sincerely
