For part timers, the union is good for one thing, rather you join or not. They keep out the temporary employment services. Most warehouse jobs in the DFW area has in-house temp services. For example, FedEx used WesStaff Service back in 2004 having an office at the FedEx hub.
I'll now address how temp services are an absolute nightmare for both supervisors and grunts.
For supervisors, you will never know what help will show up. On one day, you may get 30 people show up for your belt while only needing 20. So you send 10 away with no work. The next day you may only have 10 people for your belt because those 10 people you sent away will not likely come back for work the next day. The other 10 may either get reassigned, terminated, or quit. I'm sorry to say UPS treats supervisors very badly as it is. Can't imagine what life would be like as a supervisor with a temp service in the house.
For grunts, you can and will be let go at anytime for any reason or no reason at all. One day, there will be no work. The next day, you could be stuck for 12 hours because very few workers are available. Keeping and maintaining a schedule outside of work will be impossible under these circumstances. What if you need a simple accommodation under ADA? You will be let go. Someone does not like you; you will be let go.
The question is should you join the union? If you are part time, probably not. There are very little language of protection addressing part timers to begin with. The number of combo jobs are fast disappearing so the ability to call a strike has all but diminished. If you are full time combo or driver, definitely yes. My personal decision to not join is over not getting 10 minute relief breaks when working more than 3 hours. It is purely a personal decision going back 16 years when working for Krogers under the United Food and Commercial Workers Union. I do not pay union dues when having to work without any kind of rest break. Should that change in the next contract or be updated in the supplement for the DFW Air Hub, I will certainly change my mind.
FYI, we are working 5 hours or more at the DFW Air Hub with NO
ING BREAKS!!! If you work at this hub, check the PCMs before signing. If they mention hydration, getting enough rest at night, nutrition, DO NOT SIGN!!
