When you get back just backdate the jobs list date...... I.e if you go on Holiday on the 1st and come back on the 14th then just print off the jobs that were due up to the 7th and do them, then the next week print off the ones due up to the 14th and then on week 3 the 2 weekly ones should all be in sinc again. Just keep doing it till they are all done.
Just remember that when you are going through the days work you click "done today" that way the ones that were due on the 1st but done on the 14th will then be listed as ready to do on the 28th
