how many social workers does it take to change a lightbulb?

...four, apparently. An recent advert depicted a social worker changing an elderly man's lightbulb, thus preventing him havinmg a panic attack due to being left in the dark. Cue Hackney council's Health and Safety executive (I believe it was Hackney; It may have been another London Borough). They stated that, in order to change said lightbulb, you would need one person to change it, another to hold the stepladder steady (a stepladder is requisite to avoid back injuries), one more to turn the light switch on and off as required, and one more to comfort the elderly person being looked after by the original social worker, just in case he/she felt distressed or alarmed by the lighbulb changing event!
a caring, sharing society is a fine and good thing, but this is just bollocks.
