Not one thing about this company is professional.
The managers are heartless and DO NOT CARE about their staff.
It seems like the kind of company that would hire a manager because he goes golfing with another manager.
EVERY WEEK there is a problem with YOUR wages that you literally have to annoy them into giving it to you.
As for overtime, goodluck. Overtime is calculated over 6 weeks WHICH WAS NOT AGREED UPON BY EMPLOYEES FIRST!! Sunday pay ? Extra 5euro PER DAY not per hour.
If you have any kind of issue you would be lucky to get a reply from your site manager for at least 3 days and even at that they will try their best to turn the blame on to you.
They go through every loophole they can find to save themselves money (overtime).
If you pull them up on anything they will will try their very best to punish you in anyway they can, i.e, drop your hours.
Please, please please, if you are desperate for a job please go elsewhere, please take my advice and save your dignity.
