Well, my April 1st was very serious, and sucked bum.
I was woken up by a call at 6am (ish) by one of our US employees, saying that someone had lost their net connection and could I help find shift cover please?
I sorted everything out, finished by about 7:30am. Decided that I would be too tired to teach my lesson at 11:30am, so texted the organiser with apologies and went back to sleep. (Tuesdays are my lie-in day.) As I wouldn't be teaching, I could sleep until 2pm, and start work at 3pm.
Got a call at half nine, asking me if I had sent out a press release for this thing I was meant to send out. My answer "No. I was asleep".
So I spent the next two hours e-mailing journalists etc etc.
Went back to sleep.
Was woken up by a call at about 12 noon, by one of our Spanish UK employees, asking when he would be paid and also that he had lost his net connection.

So I went online, made sure that all his shifts were covered (he didn't actually have any shifts for that day) and by that time I only really had time to have some lunch and then start work at 3pm.
The line from Clerks "I'm not even supposed to BE here today!" came to mind, frequently.
So yeah. My start to the month was far from fun and games!
