Hi,
I have learned quite a bit about staff in the last two year, so my advice is based on my experience.
Do not get invoved with cash in hand, you will get the benift people sraight on your back.
If some is on benefit, you can employ them (part-time) bu they have to declare their earnings to the benefit agency.
Always make sure you get a national insurance number.
I advertise in my local shops or the shops near the place of work. did try the job centre, but you end up interviewing people that do not realy want the job.
I always pay people for the week they have worked, make life easier when it comes to record keeping.
When I interview I always ask if they can drive, as this is a bonus, (but if they use there own car to travel to and from different places of work they will need class 1 business ins. the upgrade is usally free or small charge)
I always ask for references and take them up and I like to have people police check too.
Wage depend on where you are based, anything from the minimum wage, but most seem to find around £5 per hour is fair. But I always put people on probation for up to three month and a start rate of £4.50 per hour.
Who not to employ, well you have to use your own judgement on that, but avoid anyone with a criminal past, do not fall for 'Im a reformed character' I did and reform was not the word this person got caught with his hand in the till (so to speak) and could have cost me a big contract.
Hope all this helps
Petra
