I've mentioned this before, but I'm still seeing many jobseekers violating this simple rule in online jobsearch groups that will help them gain a job:
be nice, be positive. Employers might not comment, they might not even have a vacancy at the present moment, but they
are watching and taking mental note, and in doing so, they are forming an impression about your behaviour, your personality, your potential suitability for vacancies they have (now and in the future).
I hope it is a good one?
But, don't just take my word for it. Publishers advise this same thing to authors, teachers advise this to students, parents to their children.
And, author Jonathan Maberry worded in a way that had Smashwords CEO reiterate it on his blog:
Do you want to be the person that onlookers form bad impressions of? Do you want to be the person that misses out on a job simply because two months ago you got into an online verbal tassle with another jobseeker or shared your negative personal tirade on 'the state of things' because you were having a bad day?
Please consider the long and short term consequences your behaviour in social media can have.
