So we start out with this snippet of info
Then it's £223 for an xmas day with no idea of call outs
Then we get to this which is a 7.5 hr decent rate + 14 hrs at £4.66. It would have to be some decent rate to cover the crap call out
I have worked many call outs some as little as 40 mins home to job and home and others that were 3 and 4 hours the longest was 8:30am call out on a Sunday getting home at 22:30 and one thing is for sure £4.66/hr wouldn't cut it
At the figures you quote something is missing 15 call outs a week works out at £36.65 per call out and nothing for the standby at what you say you are paid. There really is something missing here with the drip fed info
