How will these time requirements for ranch work fit into your life?

As a cooperative, we don’t employ hired help.

As a member, your commitment to the work is essential.
All members should have willingness
To be collaborative and collegial, even in conditions of conflict or disagreement
To accept operational decisions, especially when such decisions run counter to your own beliefs on the issue
To accept a variety of approaches to horse care and horsemanship
To be friendly and decent with all members

How will you deal with disagreements?  Are you comfortable with democratic decision making?  Are you comfortable “counting to ten” if conflict arises?

In 2010, OHA adopted our Culture of Cooperation.

As a cooperative, we are egalitarian, we contribute equitably and democratically.  There is no “ultimate authority”.

When members have divergent ideas on how to proceed, decisions take time, and emotions can run high.

As a member, you must have the ability to temper your behavior, no matter how strongly you feel.
