Typical management answer?
I do care and I do care about safety of employees very much.
The most reasonable control to safe guarding the employees from and preventing heat related illness and injury would be to air condition the facilities and and to air condition the vehicles.
You were however talking about reducing the work load.
If everyone followed the heat related illness/injury training to the letter and applied for all already established work reduction language then IMO things would definitely change regarding work load over time.
Unfortunately, both of these possible prevention measures would take something that I haven't seen for a long time from the supposed Union brothers at UPS or on the BC. Solidarity.
The word "everyone" in this post is the key.
Good luck with that. Unfortunately.
I get it. Everyone needs to stop working and find a cool place to rest when feeling the effects of heat index exhaustion. Everyone.
Add to that the 9.5 language and the company will pull it's hair out.
This takes spine. Spine that's not readily apparent in most driver groups.
The lack of AC in PCs is a bargaining issue. That takes spine too. Good luck with that. Can't even get the straight trucks used for feeder runs equipped with AC. Who's fault is that?
Let's review:
1.) Work at a pace that keeps yourself cooler in high heat indexes. (Can't say "show down".) Take multiple breaks to cool off.
2.) Get on the 9.5 opt in list when you get violated the first week. File for every violation after that.
3.) Demand your local union address the AC and poor ventilation issue in 2018.
and...
4). Open all the doors at every stop to let cooler air flow permeate the rear area while you select packages. Close all the doors when you leave the truck.
That work for you?
