If it was me i would be thinking,
what am i provided by the company ?
clothing, tools, van, diesel, training, holiday pay.
What do you have to do ?
are you working for a big company where you can get lost on site for 5 days of the week doing sweet FA and then book in for over time at the weekend OR are you running jobs, collecting other workers, feeling pressure to get things done.
what can i earn working for another company doing a similar or different role?
Sometimes less wages can be a better deal with all the other factors thrown in.
Can I get a better deal?
ask for better terms and if they can not deliver then move on to greener pastures
For example:
i am self employed: Say i earn £8-900 in 5 days which seems good at first, but then i have £100 a week in overheads for running my own operation, can do £100 a week in diesel, can spend 2-8 hours doing paperwork, no holiday pay etc. After looking at my costs, working for a firm where i have no worries and just collect wages looks quite attractive. I can earn more, make more on materials, so for me having the freedom to choose what i want to do suits my lifestyle.
Most firms will try to pay staff as little as possible, and all us sparks want to earn as much as possible.
I know a lot of firms that only pay £10-£15 an hour.
Last week i was offered £350 a day plus parking to work in London for a guy that supplies and installs machinery, but it is long hard days, i dont know how long he would take to pay it (if at all), and worst of all i am too busy to take him up on his offer. ( i did say i would be interested in the new year)
