If you are a candidate, here is a really great example in showcasing how easily this can happen.
In our office right now, we have a fabulous temporary assisting us with cleaning up our database. It is a mundane job, boring, tedious, likely OK for a few days but a few weeks – that can be a hard slog in maintaining reliability, accuracy, motivation, attention to detail and that great happy demeanour.
Initially, we only needed this assistance for a short period of time; however, as we are becoming busier and busier and we look to the future, we know we will need additional support next year.
This temporary is studying and can only make herself available for us three days a week in the new year. If you were recruiting for me and said at the beginning of a process that you had a candidate who could only commit to full-time hours during their university break and otherwise it’s three days, I would have said, I don’t think that will work (apparently, I can be our most difficult client!).
