Which station did/do you work at???
When I worked for servisair at Cardiff, the shift pattern was all over the shop. For example, these are my shifts from my last week as a dispatcher with servisair:-
Mon: off
Tue: off
Wed: 0200-1000
Thu: 0500-1330
Fri: 1100-1500
Sat: 1200-2100
Sun: 1030-1930
Pretty crap so dont plan a social life. You will also be contracted for 25 hours per week. So in the winter expect pointless 4 hour shifts (if you are kept on).
