Python multi-threading missing jobs

Question

If I run the script step by step works perfectly, but when I'm using threading misses 50-60%. I'm using Python + mechanize module

#setting up the browser
mySite = 'http://example.com/managament.php?'
postData = {'UserID' : '', 'Action':'Delete'}
job_tab1_user1 = [1,2,3]
job_tab2_user1 = [4,5,6]
job_tab1_user2 = [7,8,9]
job_tab2_user2 = [10,12,13]
.... till user1000
#i want to point out that the lists are 100% different
def user1_jobs:
    for i in job_tab1_user1:
        browser.open("http://example.com/jobs.php?actions="+i) 
        browser.open(mySite, Post_data)
    for i in job_tab2_user1:
        browser.open("http://example.com/jobs.php?actions="+i) 
        browser.open(mySite, Post_data)
def user2_jobs:
    for i in job_tab1_user2:
        browser.open("http://example.com/jobs.php?actions="+i) 
        browser.open(mySite, Post_data)
    for i in job_tab2_user2:
        browser.open("http://example.com/jobs.php?actions="+i) 
        browser.open(mySite, Post_data)
... and so on till user 1000

And I call them in the end like this:

t_user1 = threading.Thread(target=user1_jobs, args=[])
t_user1.start()
t_user2 = threading.Thread(target=user2_jobs, args=[])
t_user2.start()

I have a similar script that sends like 200 request per second and all of them are processed. I also tried using time.sleep(2), but again is missing a lot. Another question besides what is wrong with my script is if its way to compact this code, because I'm using 1000 users and the script reaches thousands of lines. Thank you in advance.

from threading import *

submits = [[1,2,3], [3,4,5], [6,7,8]]    

class worker(Thread):
    def __init__(self, site, postdata, data):
        Thread.__init__(self)
        self.data = data
        self.site = site
        self.postdata = postdata
        self.start()
    def run(self):
        for i in self.data:
            browser.open("http://example.com/jobs.php?actions="+str(i))
            browser.open(self.site, self.postdata)
for obj in submits:
    worker('http://example.com/managament.php?', {'UserID' : '', 'Action':'Delete'}, submits)

Since the OP asked for it, here's a condensed/compressed version of the code.

or:

for index in range(0,1000):
    worker('http://example.com/managament.php?', {'UserID' : '', 'Action':'Delete'}, [i for i in range(1,4)])

If the data you want to send actually is a sequence of 3 integers (1,2,3) that inclines in a perfect order.
