Your talking the UK here mate not Belguim. The statutory is 28 days for a FTE.
Normally a contractor accrue's leave as part of the contract (in the airline i work for 2 days a month so 12 for 6 months contract). If no leave is included in the contract then by extending it another 6 months and only giving 7 days is a bit stingy and i guess you'll also get it in November when no-one normally wants leave. However i suspect if you've been getting more than min days off EZY might suggest that some of these days can count towards the 28 minimum. Either way i'd get some advice on it as it doesn't sound right.
