Employees are protected against unlawful deductions from their wages.
A deduction is only lawful only if the the employee has agreed to in writing, this does include signing a contract of employment which contains any points covering additional deductions.
But then , even if there is no deductions clause, the only time an employer can still be able to make the deductions, is when it concerns the recovery of overpayments. there is an exception in law for this only .
please bear in mind I'm no expert in law ( like the title asks
But at this actual moment in time I am going though a very similar situation for my daughter. so have done a fair bit of swoting on this !!!
And the company mentioned here seem not to be UK based
Does Uk law apply here .. would hope so ?
