Spontaneous goodwill upgrades are dead as dodos on most airlines now. Management wants to see justification from the staff to ensure they're not giving to their friends instead of customers who have offered to pay or redeem credits.
I suspect I don't even get upgrades that I've filed eUpgrade requests for. I think they call names and give them to people who answer the pages. I've been told at check-in "looks good" and then at the gate "haha no chance". I make them aware I won't hear my name if they call it, and they sneer at me like I am nagging. I do get some upgrades (including one op-up after IRROPS), but those were all either in advance or confirmed in the lounge. Whereas they know what to do about wheelchairs, I think some stations can't be bothered with communication accessibility.
