What you want me to do!!!!

I really don't understand,
how you manage your staff?
you make me so suffer here.

When I'm in operation department,
you said u want me learn more things,
then i need to transfer to credit dept
I'm very happy, because i think i can concentrate on my work.

At the same time,
front-line  not enough staff,
you want me relief them when they go out lunch,
until they all came back only i go for lunch,
Even 2.30pm or 3pm,
i'm the last person go out.
After lunch i have to go back cr dept again
to continue my work.

You said front-line really shortage of staff,
the "QMS" result very very bad.
then you want me transfer back to front-line.

1 year later, some staff promoted and transfer out,
you said since cr dept shortage of staff,
and the "QMS" also no improved,
you want me open counter until 4pm
after balancing, want me to relief cr dept again
 is ok for me to do that, i accept, BUT...
until what time i can go back?
Cr dept pending a lot of work,
and u want me help up then until what time??
somemore if cr dept no clerk or on leave,
you also dun let me full time at cr dept
keep continue going up n down like dis,
it will pending a lot a lot a lot of work for me to do..
when can clear all dis??

Not because of OT,
I need time to rest....
6 1/2 hours attend customer, help u all to push "QMS",  3 hours relief cr dept,
sometime work untill 8pm... 12 hours at office...
don't you really duno i'm tired??

Until when i can stop doing this,
going up and down everyday..
shortage of staff is your problem,
i'm only the clerk, y u choose me?? but not others??
