Rejected petition probation period crackdown

The government needs to crackdown on employers abuse of probation periods.
So many employers now hire new staff, put them on probation and then sack them at the end of it with no intention to keep them in the first place.
Managers do this for a variety of reasons (ie) to get emergency staff for busy periods (eg) Christmas.
To avoid paying sick pay and holiday pay.
They can also not give any reason for sacking you, leaving the employee with a difficult situation in future interviews about why they left thier last job.
The government should either force companies to give reasons for termination of employment during probation.
Give employees right to file for unfair dismissal during probation if they can prove thier manager never intended to hire them at all.
Or scrap probation periods altogether.
Stop managers abusing the use of probation periods.
