Hundreds of people flocked to Reid Park on Monday for the 22nd annual Labor Day Picnic.
The Pima Area Labor Federation hosted the event with free food, drinks and activities. PALF says Labor Day is a day to emphasize the importance of unions and the work they do.
This year's theme was #UnionsChangeLives and #UnionsProtectOurFamilies.
There was also a classic car and motorcycle show at the park.
