work during each year.

for ex. for year 8 I have 419 persons  have worked ever, and I have
220 per.(128+92) that have worked only 1 year. How I can joint the tab
in stata?

Below I create two files, to be combined (append). If I understand you
right, a -nevemplo- value of 5 means 8-5 = 3 years of employment, so
the calculation of the corresponding -emplo- is straightforward:

clear
input emplo n
1 128
2 115
3 136
4 124
5 125
6 115
7 188
8 419
end
expand n
drop n
save emplo.dta, replace

clear
input nevemplo n
1 76
2 74
3 78
4 61
5 66
6 67
7 92
8 176
end
expand n
drop n
gen emplo = 8-nevemplo
append using emplo.dta

. tab1 emplo

-> tabulation of emplo

emplo |      Freq.     Percent        Cum.
------------+-----------------------------------
0 |        176        8.63        8.63
1 |        220       10.78       19.41
2 |        182        8.92       28.33
3 |        202        9.90       38.24
4 |        185        9.07       47.30
5 |        203        9.95       57.25
6 |        189        9.26       66.52
7 |        264       12.94       79.46
8 |        419       20.54      100.00
------------+-----------------------------------
Total |      2,040      100.00

Hope this helps
