currently i'm clearing my leave for ord and i'm abt to go for an overseas trip this week. for the 4 days trip, the 1st three days are on my leaves but the last day is on my 'off'. in fact i will arrive in singapore at abt 4pm on the last day. i'm told tt we r not allowed to go overseas on an 'off' day but i've tried calling my s1 branch for the whole day to change my leave and no one pick up the call... haiz, dunno what's wrong wif the s1 branch... now dunno wat to do as i had already booked the trip and everything...
