There are a few buzzwords you can drop to get things moving if you're actually feeling uncomfortable
You're being singled out - You actually ask everybody, just like your peers, but for some reason you're the only one being talked to
Coached on-stage - These conversations have happened in front of guests, in front of peers. Guests have commented on them, peers have commented on them. Not brand at all.
Termination mentioned without any kind of corrective action - There are very few behaviors that result in an instant termination. Redcards are not one of them. If you can link a coaching with a leader mentioning "termination" with more than one person backing you up, you probably have a hotline call on your hands. Termination conversations are reserved for final written warnings.
But these have to be clear cut, to the letter, conversations between your leaders and staff. Saying things like "You need to get redcards, or I don't know what corporate will do" or "I need you to hit this goal or I'll have to mention you as not meeting daily goals on our conference call" don't count. Your leader needs to say "If you do not get 5 redcards, you will not have a job" or similar.
