Job Hopping and its Consequences

I recently received an email asking for an advice. The sender was having a hard time getting a job due to what he thinks is his job-hopping record. Here’s the letter below:

“Hello Coach. I saw your article (in) the Manila Bulletin (Classifieds) and (it’s) nice to have tips like how to determine (if you are about to receive) a successful job offer. I believe you also welcome giving out advice to some people having a hard time getting a job because of (reasons) like: a number of previous short work periods or, should we shall we call it “job-hopping” due to conflicts. And now, it will have a negative effect (on my) future applications. Sir, what can you say about it and can it be resolved?”
