I am LHS 320 based in the UK. I am 75% part time fixed days and work almost exclusively Monday Tuesday and Wednesday and will continue to do so indefinitely.
last year I earned approx £110k (including a 5% bonus which may well not be repeated) plus 7% pension.
I can honestly say there isn’t a job I would swap this for. Sure I’d love to spend a few days getting paid to sit on the beach but you can’t have it all.
