People are human. But work is work. The canonical point of a workplace is to come together to fulfill the aims of the entrepreneurs. The personal aims of the workers are fulfilled best outside of work. Just stop to think about it logically for a minute... is the workplace the best place to circulate a petition condemning something that has nothing to do with work? The workplace necessarily is going to bring together…
We've set commerce at the center of our society and gone so far as to grant corporations "personhood", allowing them to wield enormous political influence. As such, they're able to donate unlimited sums of money under the guise of "free speech". With regard to its effect on the spirit of a functioning democracy, this is illogical to say the least.
To some extent, this outsized influence disenfranchises the citizen voter. So, given this system, it's actually quite logical for workers to express their social/political preferences through the corporations for which they work. It's a means of reclaiming some of their power by influencing an entity that itself has more influence.
If this deference to corporations were not the case, then I might be inclined to agree with you.

At least here in the U.S., our work-life balance is totally out of whack. We're expected to give so much to employers and invest so much of ourselves in the success of the company. We take time away from our families, etc. As such, the lines between our personal and work lives are already quite blurred. So I think this is where it seems strange to some that they are expected to leave select parts of their personal lives at the door.
