Jim.. before you do any long term or permanent buggering off...

As a tradesman of many years, you should be well aware of how 'constructive dismissal' works...

Don't give the rotters who want you gone,
the satisfaction of you leaving because they made you too fed up to stay...

Where my mrs works in LEA, we can see good older experienced workers
taking early retirement, or resigning,
because the job has been deliberately made so stressful they can't cope any more,
Thus saving the bosses the expense and blame of making them redundant,
or finding petty pretences to sack them......

When they tried it on with my mrs, I convinced her to get her union rep involved and fight back...

That was a very distressing few months of struggle..

After that, the bosses have left her alone and picked on weaker individuals...
