After being posted in Kingston for 7 years, I have an idea what unit(s) we're dealing with. I remember having to sit in a locked room every afternoon for a month auditing Sick Parade registers and cross referencing nominal rolls, looking for patterns from a sub-unit of a major lodger unit in Kingston (cough, CFSCE, cough) due to abuses of authority within one of the squadrons that lead to an almost 100% sick parade rate within that sub unit leading to countless days of sick leave. Most of the complaints, as one might guess, were MH related...
Anyway, a mere Major, unless even if they are a Commanding Officer, does not have the authority to make such, hmmm, silly policies. He does have the right to demand that you check in with the duty staff to say you're going on Sick Parade so that you are accounted for, however, they don't have the right to know as to why you're going...you're allowed to volunteer that if you choose, but they really have no right to ask. A Commanding Officer is allowed to discuss generalities of someone's condition with an MO or medical staff, but that is pretty much limited to what's in the aforementioned policies Occam brought forth. Essentially, "Bloggins is broken, here's what they can and can't do and for how long".
I think the first time this Maj is subject to his/her own policy and has to divulge to the duty staff that they're going to go on Sick Parade because "I'm peeing razor blades and have a weird drip that won't go away", they'll rethink their policy...
