Depends, did you used to work as a milkman and paid for one of those correspondence courses? If so you must be worth at least £35k now…
As for salary banding, coincidentally my place is going through the same exercise at the moment although they’ve paid some agency (probably a fortune) to work it all out. They also seem to be proud it will all be based on national averages – then again, “proud to be average” just about sums up most of my experiences with HR types.
Not actually sure what the impact will be for us, they used to publish salary bands on our intranet until people started complaining they were below the minimum salary for their grade so rather than actually address this they just stopped publishing the bands.
We’re an outsourcer as well though so we do ‘acquire’ people from time to time on grossly inflated salaries (until recently I was the third highest paid person in my team, despite being the team leader, most experienced and technically qualified…). So unless you think you’re grossly over-paid I wouldn’t really worry about getting managed out, especially if your boss appreciates you (not that that counts for much if the budget-cutting knives come out…).
