"Amazon sacks employees who publicly expressed their support for Yellow Vests' blockages"
So that doesn't seem to be 'calling on people' to bring material as you wrote in your previous post. I'm also unsure if your post is referring to employees directly partaking in blockading? Please clarify we are on the same page here, because as far as I'm concerned, this is supporting, not partaking.
I wont argue with you regarding the nature of 'blockage' because I don't know but 'blockages' could mean picketing or blockading to me.
which translates roughly to: "It takes reinforcement and pallets, friends!"
That is what I read as "calling on people to bring blockade materials." (My French is somewhat halting and far from fluent, but I don't think I've mis-understood here.)
Pallets don't have a place in free speech/supportable picketing, IMO. They do have a place in illegal blockades.
Pallets certainly don't say blockade to me.
So again that could be read either way.
Blockading access to the site and impeding operations goes beyond legal/supportable picketing. This I do not support and would support an employer who sacks an employee for it.
