doll Post a link to this thread in the employment section - there's a number of sound employment lawyers over there (am a lawyer but have a rusty masters in employment but there are others over there with good current up to date knowledge)
So rusty disclaimer up front (!) I would agree with other posters saying there is definitely a big question mark over DD's employment status and this matters because whether she is employed by the salon or not will determine who should have what insurance etc.
Things that make DD an employee
Withholding 'wages'
Contractual hours
Things that suggest she is self-employed
Pays own NI & Tax (IR35 Taxation rule applies)
Paying rent for the chair
What are the wierd things in the contract? They could help with sorting out her employment status.
Is there a local law centre you can go to? Often best to phone in advance and see when/if they have any employment experts available at particular times. Will try and find a link for the Law Centre Federation thingy.
Best thing DD can do for the moment before she can take advice is to get writing! Get her to write down the chronology of everything and everything she can remember them saying to her, e.g. from applying for the job (is there an advert? What did it say?), to interview, to signing contract etc. Obv anything regarding insurance is v important but also what training/induction was there bearing in mind she is fresh out of college? Is the fact that she is fresh out of college clear on her CV?
