Worksite 5 Executive Committee – PDF download

Karen Sadler


A graduate in 1985 of the former St. Boniface General Hospital School of Nursing RN Program, I have walked these halls at SBH except for 3 years (87-90) when I worked at the Churchill Health Centre as a result of my husband’s job transfer.
I became union aware and “active” when MNU went out on strike, January 1st , 1991, and have not looked back.

I started as a unit rep and then in time was elected as the worksite 5 secretary, then as the worksite 5 vice president and have had the ultimate honour of representing the members of worksite 5 as their president since 2011.
I have been part of the Provincial Collective Bargaining Committee, negotiating the last two collective agreements: April 1, 2013- March 31, 2017 & April 1, 2017- March 31, 2024.
The best part of my role by far, is meeting the members of Worksite 5.

Sheila Holden

Vice President

I began my career in health care working as a health care aide and then a ward clerk at the Misericordia Hospital from 1979 until I graduated from the St. Boniface School of Nursing in 1988 with a diploma in nursing. I began nursing in Medicine. 
In 1990 I began attending union meetings.  The Gary Filman’s Conservative government was in power and job action was imminent.

At that time there was no e-mail so to know what was going on I had to
go to meetings.

January 1st, 1991, at 6:00 AM Manitoba Nurses Union went on strike.
From that point on I was involved in the union as a volunteer.  I have held positions as union Rep, WSR
committee member, secretary, vice president, co-treasurer and board member.  I have attended
numerous labor schools, Local 5 AGMs, MNU AGMs, CFNUs and one Global Nurse United meeting.  I
have also graduated with a post RN BN.
I am currently Worksite 5 Vice President, and the best part of every day is meeting and speaking to

Tracey Busby

Executive Assistant

I have over 25 years of experience in office administration in both health care and working in a union setting. As an ally of nurses and the labour movement, for as long as I can remember, joining St Boniface Nurses in May 2022 felt like a very natural fit.

I am actively involved in my own union COPE342, as a trustee, and so I am lucky to view the role of the union from a variety of lenses.
