I'm a Line holder this month, on RES next month. I don't have the PWA or SRH handy...

Yesterday I get a call from CS (I'm off) and just assumed it was another IA call. Instead it was CS placing a line check trip, over 30 days out, on my schedule on one of my LC days. I'm guessing it's legal since it seems like they have carte blanche on anything training related? It's just a one day trip and pretty easy but still seems unusual. I of course have not acknowledged anything. Does this count as proper notification?
