The Alberta Federation of Labour is celebrating the work of unions in the province in its centennial anniversary.
President of the AFL Gil McGowan says labour laws and work conditions have improved dramatically in the past 100 years however he has some reservations.
"We are concerned that there're are forces out there, both political and ideological forces that want to tip the playing field more dramatically in favour of employers at the expense of working people.
McGowan says over the last 100 years unions worked to established minimum wage, the 8-hour work day, vacations and pensions.
The AFL is celebrating its centennial down at Fort Edmonton Park Saturday. Festivities go until 11:30pm.
