The correct answer to this open question is the following.
Unfortunately, you did not include the name of the two labor organizations. There is no further context, reference, text, or article.
However, trying to help you we can comment on the following.
Probably, you are referring to the Ontario Federation of Labor (OFL) and the Ontario Public ServiceEmployees Union (OPSEU).
If that is the case, we say that these two labor organizations have a major role in supporting the employees of Tim Horton's branches, after the response, they have taken in Ontario regarding the increase of the minimum wage in that Canadian province.
The power of these labor organizations created awareness of the employee's situation when different media channels covered the news about the demonstrations. This coverage was nationwide, alerting all Canadians about the situation in some branches of this famous and cherished Canadian fast-food restaurant.
This situation does not only grab the attention of public opinion but from the government and political parties that can get into the discussion, affecting the public image and reputation of Tim Horton.
